RECOMMENDED RULES FOR SIZING THE WATER SUPPLY SYSTEM

A 4.2 If Where copper tubing or brass pipe is to be used for the supply piping and if the character of the water is such that onlyslight changes in the hydraulic characteristics may be are expected, Chart A-4 4.1 shall be permitted to be used.

20

A 4.3 Chart A-5 4.1(1) should shall be used for ferrous pipe with only the most favorable water supply in regards to corrosionand caking. If Where the water is hard or corrosive, Chart A-6 4.1(2) or A-7 4.1(3) will be applicable. For extremely hard water,it will be advisable to make additional allowances for the reduction of capacity of hot-water lines in service.

A 5.2 Fixture branches to the building supply, if where they are sized for the same permissible friction loss per one-hundred(100) feet (30,480 mm) of pipe as the branches and risers to the highest level in the building, may lead to inadequate water supplyto the upper floor of a building. This may shall be controlled by the following:

(1) sSelecting the sizes of pipe for the different branches so that the total friction loss in each lower branch is approximatelyequal to the total loss in the riser, including both friction loss and loss in static pressure;.

(2) tThrottling each such branch by means of a valve until the preceding balance is obtained;.

(3) iIncreasing the size of the building supply and risers above the minimum required to meet the maximum permissible fric-tion loss.

A 6.2 If Where a pressure-reducing valve is used in the building supply, the developed length of supply piping and the permis-sible friction loss should shall be computed from the building side of the valve.

ExPLANATORY NOTES ON COMBINATION WASTE AND VENT SYSTEMS

(See Section 910.0 of the UPC for specific limitations.)

B 1.0 Combination waste and vent systems, as outlined in Section 910.0 of this code, cover the horizontal wet venting of a seriesof traps by means of a common waste and vent pipe. Pipe sizes at least not less than two (2) pipe sizes larger than those requiredfor a conventional system are designed to maintain a wetted perimeter or flow line low enough in the waste pipe to allowadequate air movement in the upper portion, thus balancing the system. Sinks, lavatories, and other fixtures that rough in abovethe floor, should shall not be permitted on a combination waste and vent system, which, at best, is merely an expedient designedto be used in locations where it would be structurally impractical to provide venting in the conventional manner.

Combination waste and vent systems are intended primarily for extensive floor or shower drain installations where sepa-rate venting is not practical, for floor sinks in markets, demonstration or work tables in school buildings, or for similar appli-cations where the fixtures are not adjacent to walls or partitions. Due to its oversize characteristics, such a waste system is notself-scouring and, consequently, care should shall be exercised as to the type of fixtures connected thereto and to the locationof cleanouts. In view of its grease-producing potential, restaurant kitchen equipment should shall not be connected to a combi-nation waste and vent system.

B 2.0 Caution must be exercised to exclude appurtenances delivering large quantities or surges of water (such as pumps, sandinterceptors, etc.) from combination waste and vent systems in order that adequate venting will be maintained. Small fixtureswith a waste-producing potential of less than seven and one-half (71⁄2) gallons per minute (gpm) (28.4 L/min. 0.47 L/s) shall bepermitted to be safely assigned a loading value of one (1) unit. Long runs should shall be laid at the minimum permissible slopein order to keep tailpieces as short as possible. Tailpieces should shall not exceed two (2) feet (610 mm) in length, which mayshall necessitate slopes up to forty-five (45) degrees (0.79 rad) (see definition of horizontal pipe) on some branches.

B 3.0 It is essential that the pneumatics of such a system be properly engineered, as the air pressure within the line must shallat all times balance that of outside atmosphere in order to prevent either trap seal loss or air locking between traps. Long mainsshall be provided with additional relief vents located at intervals not exceeding one-hundred (100) feet (30,480 mm). Each suchrelief vent should shall equal at least not less than one-half (1/2) of the inside cross-sectional area of the drain pipe served.

B 4.0 Trap sizes are required to be equivalent to the branches they serve (two (2) pipe sizes larger than normal), and tailpiecesbetween fixtures or floor drains and such traps should shall be reduced to normal size.

B 5.0 Duplicate layout drawings of each such proposed piping system must shall be presented to the Authority Having Juris-diction and approval obtained before any an installation is made. Complicated layouts should shall be checked by qualifiedpersonnel.

21

B 5.1 Example of Sizing.

A floor drain normally requires a two (2) inch (50 mm) trap and waste. On a combination waste and vent system, both trap andwaste must shall be increased two (2) pipe sizes (through 2-“inches and 3“inches) (65 50 mm and 80 mm), which would makethe trap three (3) inches (80 mm). Pipe sizes recognized for this purpose are 2 inches., 2-1⁄2 inches., 3 inches., 3-1⁄2 inches., 4inches., 4-1⁄2 inches., 5 inches., 6 inches., etc. (50 mm, 65 mm, 80 mm, 90 mm, 100 mm, 115 mm, 125 mm, 150 mm, etc.). Thetailpiece between the floor drain and its trap should shall be two (2) inches (50 mm) (or normal size) to ensure that the amountof wastewater entering the trap only partially fills the waste branch. A three (3) inch (80 mm) floor drain would thus require afour (4) inch (100 mm) trap, a four (4) inch (100 mm) floor drain, and five (5) inch (125 mm) trap, etc., for the reasons previ-ously stated.

The rainfall rates in Table D-1.0 should shall be permitted to be used for design unless higher values are established locally.

D 3.0 Sizing by Roof Area.

Storm drainage systems can be sized using the roof area served by each section of the drainage system. Maximum allowableroof areas with various rainfall rates are listed in Table 11-1 1101.11 and Table 11-2 1101.7, along with the required pipe sizes.Using this method, it may be necessary shall be permitted to interpolate between two listed rainfall rate columns (inches perhour). To determine the allowable roof area for a listed pipe size at a listed slope, divide the allowable square feet of roof for aone (1) in./hr. inch per hour (in/h) (25.4 mm/h) rainfall rate by the listed rainfall rate for the local area. For example, the allow-able roof area for a six (6) inch (150 mm) drain at one-eighth (1⁄8) inch per foot (3.2 mm 10.4 mm/m) slope with a rainfall rateof 3.2 inches (in/h) (81 mm/h) is 21,400/3.2 = 6,688 square feet (621.3 m2).

TCC COMMITTEE STATEMENT: The additional language added in Section 102.1 provides correlation between theUPC and Section 108.2 of the UMC.

The following proposed action moves forward as approved by the TCC and supersedes the recommendation fromthe UPC TC for action taken on Section 102.1 in regards to the powers of the Authority Having Jurisdiction.


PUBLIC COMMENT:

SUBMITTER: Charles Hernandez, Plumbing Manufacturers Institute

RECOMMENDATION:


101.4.1.4 Conflicts Between Codes. Where the requirements within the jurisdiction of this plumbing code conflict withthe requirements of the mechanical code, this code shall prevail. In instances where the code, applicable standards, or the manu-facturer’s instructions conflict, the more stringent provisions shall prevail. Providing the manufacturer’s warranty is not compro-mised. Where there is a conflict between a general requirement and a specific requirement, the specific requirement shall prevail.

SUBSTANTIATION:

The current language may create a “subjective interpretation”. A manufacturer’s warranty may be null and voidif local authorities overrule manufacture’s installation requirements, possibly harming the consumer by causingan unsafe condition.

COMMITTEE ACTION: Reject the public comment

45


The proposed text is overly restrictive, unenforceable, and subjective. Such language may lead to non-uniformenforcement. In addition, there are no means to establish compliance or conflicts between the code and themanufacturer’s warranty.

UPC 2012 – (203.0):

SUBMITTER: Jack BeuschelStudor, Inc.

RECOMMENDATION:

Add new text as follows:

203.0

Air Admittance Valves. One-way valves designed to allow air to enter the plumbing drainage system when negative pres-sures develop in the piping system. The device closes by gravity, seals the vent terminal at zero differential pressure (no flowconditions) and under positive internal pressures. The purpose of an air admittance valve is to provide a method of allowing airto enter the plumbing drainage system to prevent siphonage of plumbing fixture traps.

SUBSTANTIATION:

In plumbing installations it has been necessary to extend vent pipes to the atmosphere. This has resulted in prob-lems relating to extensive vent piping, roof penetrations requiring vent pipe flashings that eventually leak, floor pene-trations requiring fire-stopping devices, weakening of building frames, and frost closures as well as pollution of theenvironment and indoor air by sewer gas, commonly referred to as “sick building syndrome”.

Air admittance valves (AAV’s) can resolve these problems and permit a relatively easier solution than venting to theatmosphere. Since there are less open vent pipes, the possibility of water entering the building through vent piperoof flashings is substantially reduced. The AAV opens under negative pressure conditions allowing air to enter theDWV system preventing siphonage of the water trap. The valve closes by gravity under neutral and positive pres-sure, preventing the escape of sewer gas. It operates by means of a pressure/gravity-activated sealing assemblythat acts as a one-way valve. Positive pressure will find relief through the open pipe relief vent required on thebuilding drain when AAV’s are installed. Systems in which AAV’s are installed in conjunction with a minimum of oneopen vent pipe protect fixture traps against siphonage and back-pressure, and air circulation is ensured throughoutall parts of the system in compliance with the intent of Section 901.0 of the UPC. Studies have proven that byinstalling AAV’s in the DWV system both positive and negative pressure transients are reduced and better controlledthan in an open pipe vent system. Installation of AAV’s has no adverse effect on the operation of the system andprovides benefits in terms of trap seal protection under all conditions. AAV’s have been installed in Europe since 1972and in the USA since 1988. The valves have been field tested and have proven to be a safe alternative to open pipevents. The performance standards for AAV’s are ANSI/ASSE 1051 and ANSI/NSF 14. Standards ANSI/ASSE 1051and ANSI/NSF 14 have been revised and the new editions published in 2009.

PUBLIC COMMENT 1 (Assembly Action):

SUBMITTER: David Mann, Plumbers & Steamfitters Local 342

RECOMMENDATION:

Request to reject the code change proposal by this public comment.

SUBSTANTIATION:

There are no guarantees that an air admittance valve will provide adequate airflow throughout the DWV system.



VOTING RESULTS: AFFIRMATIVE: 19 NEGATIVE: 8 ABSTENTION: 1

ExPLANATION OF NEGATIVE:

BALLANCO: The one sentence substantiation is an embarrassment for the Technical Committee to consider.Furthermore, the statement is incorrect. If one took the time to read all of the justification submitted by the propo-nent, including test reports, studies, and field history, one would really understand that there is adequate justifica-tion to accept air admittance valves. Air admittance valves have been used in this country successfully for morethan 25 years. They have been used worldwide for a longer period of time. My home state of Indiana has acceptedair admittance valves since 1988. The alleged problems and catastrophic failures have not occurred as predictedby those opposed to this change.

BROWN: Air admittance valves are proven technology approved within American National Standards and otherplumbing codes. These devices have been successfully used for decades. This code should provide regulation onhow to install and use these devices.

BUUCK: The committee needs to recognize that this product is listed and certified for use through IAPMO R&T. Theargument that DWV systems where AAV’s are installed do not adequately equalize differences in pressure can berefuted by Prof. John Swaffield's book "Transient Airflow in Building Drainage Systems." His studies show thatreplacing upper open stack terminations with an AAV’s has proven effective on limiting positive air pressure transientsas well as the base stack pressure by cutting down on the volume of air in the system. Furthermore, there was notechnical documentation to support the claim made in the comment's substantiation.

CABOT: There is no technical justification to ignore the use of AAV’s in the UPC. The UPC is failing to provide guid-ance on these widely used and acceptable devices.

CHANG: Air admittance valves have been used successfully for many years and are approved within AmericanNational Standards and other North America plumbing codes.

CHURCH: Adequate technical reasons for rejection were not given.

PAPE: The opponents have not supplied valid scientific evidence that AAV's are a significantly greater health threatthan traditional venting. No venting system is fail-proof. The definitions section, Chapter 2, is not the place to debatebiases not founded on scientific evidence.

STACK: As long as there is enough venting for the rest of the home, an AAV will draw enough air to properly vent afixture.

48

ExPLANATION OF ABSTENTION:

SCARANO: I am abstaining due to my close association with a family involved with air admittance valves.

PUBLIC COMMENT 2:

SUBMITTER: Jack Beuschel, Studor, Inc.

RECOMMENDATION:

Request to replace the code change proposal by this public comment.

203.0

Air Admittance Valves. One-way valves designed to allow air to enter the plumbing drainage system when negative pres-sures develop in the piping system.

SUBSTANTIATION:

The explanation of negative centers around alleged failures during pre-installation pressure tests in Wisconsin, reliefof positive pressure and air circulation. Let me address each of these negatives.

Wisconsin

The State of Wisconsin is the only jurisdiction in the world that requires this test. The reason it is not required else-where is that all valves are tested for tightness at the manufacturing facility before packaging and shipping, and thatfield testing will not always produce accurate results as proven by the NSF test report dated March 5, 2010 (Exhibit1). This report proves that the drop in pressure indicated on the testing device is not due to a leaking air admittancevalve (AAV) but due to the cooling of air in the tester when testing is performed in the field on job sites. In June 2010the State of Wisconsin accepted the results of the NSF test report, revised the test protocol, and renewed the productapprovals for AAV’s through December 31, 2013.

Positive Pressure

All DWV systems in which AAV’s are installed require a minimum of one open vent pipe to atmosphere which willrelieve positive pressure should it develop in the system. This requirement is stated in Section 911.7 (Vent toOutdoors) in the code change proposal. Further, as stated by Professor John Swaffield (the technical advisor to theWHO and WPC) many times and most recently in his book “Transient Airflow in Building Drainage Systems”, AAV’sdrastically reduce stack airflow which in turn limits the positive air pressure transients thus lowering positive pres-sure in the system. This counters the claim that AAV systems do not relieve back pressure (transients). In fact theopposite is true that AAV’s help reduce the effect, with one open vent as required and the rest of the stacks cappedusing AAV’s, the building has greater protection against positive pressure than with open pipe vents (Exhibit 2).

DWV systems in which AAV’s are installed meet the requirements of Section 901.2 (Trap Seal Protection) sincethey prevent the trap seal from being exposed to a pressure differential that exceeds one (1) inch of a water column(249 PA) on the outlet side of the trap.

Air Circulation

There is no section in the UPC that specifies how much air circulation in terms of CFM is required in DWV systems.The only reference to air circulation is in Section 901.1 (Vents Required) and Section 1002.1 (Traps Protected byVent Pipes), but neither section specifies how much is required. Table 7-5 (Maximum Unit Loading and MaximumLength of Drainage and Vent Piping) specifies the site of drainage and vent pipes required based on DFU loadfactors. Section 1.2.3 Rating in the AAV ASSE Standards 1050 and 1051 specifies the drainage stack pipe sizerequired and maximum DFUs. A comparison of the two tables shows that the DFU load factors in AAV systems areequal to or in most cases more restrictive than open pipe systems (Exhibits 3 & 4).

The balance of the comments in the explanation of negatives are nothing more than opinions and innuendoes notsupported by documented evidence.

49



Based on the findings of Dr. Phyllis Fox, air admittance valves do not relieve positive pressure, only negative pres-sure. In addition, these products do not adequately deal with backpressure against the trap seal and are less thanequivalent to an open vent system. Therefore, a definition is not warranted.




BALLANCO: The proponent justified the inclusion of the definition for air admittance valve in the UPC.

BROWN: Air admittance valves are proven technology approved within American National Standards and otherplumbing codes. These devices have been successfully used for decades. This code should provide regulation onhow to install and use these devices.

BUUCK: The committee needs to recognize that this product is listed and certified for use through IAPMO R&T. Theargument that DWV systems where AAV’s are installed do not adequately equalize differences in pressure can berefuted by Prof. John Swaffield's book "Transient Airflow in Building Drainage Systems." His studies show thatreplacing upper open stack terminations with an AAV has proven effective on limiting positive air pressure transientsas well as the base stack pressure by cutting down on the volume of air in the system. Furthermore, the findings ofDr. Phyllis Fox referred to in the committee statement do not address the performance of AAV’s in their installed state;they address the toxicity of sewer gases and, therefore, have no bearing on this topic. An appellate court in Californiadecided in Studor's favor where her findings were used in litigation against AAV’s.

CABOT: There is no technical justification to ignore the use of AAV’s in the UPC. The UPC is failing to provide guid-ance on these widely used and acceptable devices.

CHANG: Air admittance valves have been used successfully for many years and are approved within AmericanNational Standards and other North America plumbing codes.

CHURCH: Adequate technical reasons for rejection were not provided by the TC.

PAPE: The opponents have not supplied valid scientific evidence that AAV's are a health threat. No venting systemis fail-proof. Air admittance valves are proven technology approved within standards and other plumbing codes.These devices have been successfully used for decades. This code needs to enter the 21st century.

STACK: Wake up, it's the 21st century. AAV’s are here to stay. Allow them, but have a say in how they are used.


SCARANO: I am abstaining due to my close association with a family involved with air admittance valves.

1 To be provided and installed by the utility company.2 Available static pressure after head loss.3 Building supplyWater service, not less than three-quarter (3⁄4) inch (20 mm) nominal size.

SUBSTANTIATION:

The above code revisions clarify the intent of the water supply sizing requirements of Chapter 6 which is to governonly those components of the water supply system within the scope of the UPC, irrespective of the location of themeter and provides clarification as to the specific materials utilized in such system as referenced in Table 6-4.

In Section 604.1, the reference to Table 14-1 is not necessary since NSF 61 is already listed in the section.

The intent of Table 6-6 is not to size the water meter or street service pipe since these installations are installed bythe utility company. The revisions above make it clear that the purpose for this table is to size water service and distri-bution piping.

COMMITTEE ACTION: Reject


The proposed text makes fundamental changes to the design of a water supply system, and committee preferredexisting terminology.

The TCC has the responsibility to resolve conflicts and achieve correlation among the recommendations of the TCs.The TCC shall have the authority to choose between alternative text recommended by the TC, but only as neces-sary for correlation, consistency, and the correction of errors and omissions in accordance with Section 3-4 of theRegulations Governing Committee Projects. Actions taken on UPC Item #6 “Building Supply” resulted in a conflictwithin this code. In order to correlate language the following Technical Correlating Committee proposed actionto the UPC is shown as follows:

204.0Building Supply. The pipe carrying potable water from the water meter or other source of water supply to a building or otherpoint of use or distribution on the lot. Building supply shall also mean water service.

225.0Water-Distributingon Pipe. In a building or premises, a pipe that conveys potable water from the building supply pipe tothe plumbing fixtures and other water outlets.

TCC COMMITTEE STATEMENT: The Plumbing TC rejected Item #6 that would have changed “building supply” to“water service” in various sections, but not all, throughout the UPC. The above revisions provide correlationthroughout the entire UPC by changing all references to “water service” to “building supply”.


PUBLIC COMMENT:

SUBMITTER: Julius Ballanco, American Society of Plumbing Engineers

RECOMMENDATION:

Request to accept the code change proposal as submitted by this public comment.

SUBSTANTIATION:

Item # 6 should be approved as submitted based on the following reasons:

1. The same terminology (building supply) that was used in the 1958 UPC is still being used today. The term “waterservice” is the correct terminology, and is indicated as such in several of the referenced standards in Table 6-4(i.e. ASTM B 88, ASTM F 877, ASTM F 1974, AWWA C151, AWWA C901, etc.). It should be noted that the term“building supply” is not indicated in a single standard outlined in Table 6-4.

2. The term “water service” is indicated by the other two major plumbing codes (International Plumbing Code andNational Standard Plumbing Code) as the pipe ran from the water main, or other water supply source, to thebuilding.

3. The footnote for Table 6-4 needs to be deleted since it has caused confusion amongst Authorities Having Juris-diction, plumbing contractors, and engineers. As the footnote is written, it has been interpreted that asbestos-cement, PE, and PVC can be used for cold water applications within a building. However, that is not the intentsince such piping is not designed for the pressures and temperatures that are required of piping used for waterdistribution within a building. The original intent of the footnote was to recognize that asbestos-cement, PE, andPVC are approved for cold water applications outside of a building where the risk of hot water crossover is notpossible. Therefore, since Table 6-4 deals with water distribution within a building the footnote needs to bedeleted to avoid further confusion.



The existing language is preferred over the proposed language, and the current text has not caused misapplicationsor confusion in the industry.




BALLANCO: The UPC uses the incorrect terminology. The proper term is "water service." Every other plumbingdocument refers to water service. If you read the definition of "building supply," it can also mean “water service”. Thereneeds to be a correct use of terminology in the UPC.

BROWN: This change is creating inconsistent terminology with most national standards and other model plumbingcodes.

CABOT: Water service is the commonly used term.

56

PAPE: The code needs to change its terminology to conform with the industry. "Building Supply" is an obtuse termthat needs to be updated.

TABAKH, TRAFTON: Water service is the common term used in industry. The proposal to change the title “buildingsupply pipe” to “water service” was good. This is the terminology used by the City of Los Angeles.


BEACH: The terminology should be consistent with other building and plumbing codes. However, I don't work withother plumbing codes, therefore I can't personally verify which term is consistent.

57


UPC 2012 – (208.0):



RECOMMENDATION:



208.0

Faucets. A valve end of a water pipe by means of which water can be drawn from or held within the pipe.

Metering Faucet. A faucet that after actuation dispenses water of a predetermined volume or for a predetermined periodof time for each cycle.

Self-Closing Faucet. A faucet that is designed to close itself as soon as the activating mechanism is released.

SUBSTANTIATION:

These terms are referenced in Chapter 4, and should be defined in order to apply their meaning used in the bodyof the code.



The proposed definitions are inaccurate and do not address the issues within the code. No technical substantiationhas been provided to justify that the definitions are necessary.


PUBLIC COMMENT:


RECOMMENDATION:


Faucet. A device that controls and guides the flow of water into a sink fixture.

Metering Faucet. A self-closing faucet that dispenses, for each cycle, a fixed volume of water for a fixed period of time.

Self-Closing Faucet. A faucet that closes itself after the actuation or control mechanism is deactivated.

SUBSTANTIATION:

Definition of a faucet should be harmonized with the existing standards.



The substantiation lacks technical justification in that the proposed definitions are not warranted in order to clarify the

code. The proposed definitions are subjective and confusing in that the definition for faucet only references sinks without

applications for lavatories, bathtubs, etc.

58


VOTING RESULTS: AFFIRMATIVE: 25 NEGATIVE: 3


BROWN: The UPC should utilize the definition consistent with the national standard for plumbing fixture fittings.

CHURCH: PMI's proposed definition is correct.

PAPE: The code needs to change and define its terminology to adapt, adopt, and conform to the evolving industry.

59


UPC 2012 – (TIA UPC – 001-09, Sections 211.0 and 405.2):

SUBMITTER: Lawrence BrownNational Associations of Home Builders

RECOMMENDATION:


211.0

Insanitary. A condition that is contrary to sanitary principles or is injurious to health.

Conditions to which “insanitary” shall apply include the following:

(1) Any trap that does not maintain a proper trap seal.

(2) Any opening in a drainage system, except where lawful, that is not provided with an approved liquid water sealed trap.

(3) Any plumbing fixture or other waste discharging receptor or device that is not supplied with water sufficient to flush and main-tain the fixture or receptor in a clean condition.

(3) (4) Any defective fixture, trap, pipe, or fitting.

(4) (5)Any trap, except where in this code exempted, directly connected to a drainage system, the seal of which is not protectedagainst siphonage and backpressure by a vent pipe.

(5) (6)Any connection, cross-connection, construction, or condition, temporary or permanent, that would permit or make possibleby any means whatsoever for any unapproved foreign matter to enter a water distribution system used for domestic purposes.

(6) (7) The foregoing enumeration of conditions to which the term “insanitary” shall apply, shall not preclude the application ofthat term to conditions that are, in fact, insanitary.

405.2 Prohibited Urinals. Trough urinals and urinals with an invisible seal shall be prohibited.

Exception: Non-water urinals.

SUBSTANTIATION:

Technical Merit:

This TIA is to address the conflict in the code in Sections 211.0, 1005.0 and 405.2 due to the inclusion of non-waterurinals and revising the definition of “water” seal trap to “liquid” seal trap in Section 1005.0 of the 2009 UPC. Section402.3.1 for non-water urinals was added in the 2009 UPC that allows the use and installation of non-water urinals.Non-water urinals use a barrier liquid sealant to maintain a trap seal. Non-water urinals do not have a visible sealas described in Section 405.2 therefore was revised to include an exception. Section 211.0 (3) was deleted due tothe added language and not all plumbing fixtures use water such as non-water urinals, floor drains and floor sinks.This TIA eliminates conflicting code language in the 2009 UPC.

Emergency Nature:

Per IAPMO’s Regulations Governing Committee Projects, Section 5-2, determination of an emergency nature include“the document contains a conflict within the document.” As pointed out above, there is a conflict between Sections211.0, 405.2, 1005.0 due to the inclusion of non-water urinals and revising the term “water” versus “liquid” seal traps.

COMMITTEE ACTION: Accept as Submitted


PUBLIC COMMENT (Assembly Action):

SUBMITTER: Arnold Rodio, Pace Setter Plumbing

RECOMMENDATION:


SUBSTANTIATION:

Plumbing fixtures that are not flushed with water can result in an insanitary condition.


60




BROWN: There needs to be an exemption for waterless urinals to resolve a conflict in the code.

BUUCK: The same change was fully accepted by the committee when it deliberated on the TIA. It should not bereverting its decision and thus reinstating the conflict.

PAPE: The definition should reflect the code. Chapter 2 is not the place to promote biases without evidence and re-debate an issue resolve many years ago.

Item # 17 Comment Seq # 7UPC 2012 – (222.0):



RECOMMENDATION:



222.0

Thermal Shock. A rapid change in the water temperature that is felt by the user and is sufficient to produce a potentiallyhazardous reaction.

SUBSTANTIATION:

This term is referenced in Chapter 4, and should be defined in order to apply its meaning used in the body of thecode.



The proposed definition is not needed within the UPC because it does not provide any benefits to the end user.


PUBLIC COMMENT:


RECOMMENDATION:


222.0

Thermal Shock. A rapid change in the outlet water temperature that is felt by the user and is sufficient to produce a poten-tially hazardous reaction.

SUBSTANTIATION:

The proposed definition for “thermal shock” is needed within the UPC since the term is used in Section 418.0, andis only defined currently within industry standards. This definition as written would harmonize with the definition usedin both ASSE 1016 and ASME A112.18.1/CSA B125.1 in regards to valves that provide scald and thermal shockprotection.



The proposed text does not provide additional benefits or clarification for the installation or inspection of tempera-ture control valves or devices.




CHURCH: PMI's change provides better clarity for the definition.

SUBMITTER: Rand AckroydChair, UPC Correlation Task Group

RECOMMENDATION:



301.1.4 Pipe, Tubing, and Fitting Sizes. Pipe, tubing, and fitting sizes shall be expressed in nominal sizes as referenced

in Table 1401.1 for material standards.

302.0 Iron Pipe Size (IPS) Pipe.

Iron, steel, brass, and copper pipe shall be standard- weight iron pipe size (IPS) pipe.


317.0 Increasers and Reducers.

Where different sizes of pipes and fittings are to be connected, the proper size increasers or reducers or reducing fittings shall

be used between the two sizes. Brass or cast-iron body cleanouts shall not be used as a reducer or adapter from cast-iron drainage

pipe to iron pipe size (IPS) metallic pipe.

SUBSTANTIATION:

Iron pipe size has been replaced with nominal pipe size (NPS) based on ASME B36.10 and ASME B36.19. Pipesizing is based on two non-dimensional numbers: a nominal pipe size based on inches and a schedule. In order tonot cause confusion and misapplication this term should be deleted.



PUBLIC COMMENT 1 (Assembly Action):

SUBMITTER: Arnold Rodio, Pace Setter Plumbing

RECOMMENDATION:


SUBSTANTIATION:

Iron pipe size is still recognized within the industry, and therefore should not be deleted from the UPC.





BALLANCO: Iron pipe size is an archaic term that is no longer used in codes and standards. The values in this tablecome from ASME. ASME has changed all of its standards to "nominal pipe size." ASTM has done the same. If youlook at ASTM A 53, the table states nominal pipe size. ASTM A 53 regulates steel pipe which is made from iron. Itis time for the UPC to be updated to the correct term.


BLOICE: I do not think that standards should be in the body of the code. Most plumbers that use the code don't evenknow what these standards represent.

PUBLIC COMMENT 2:

SUBMITTER: Rand Ackroyd, Rand Technical Consulting

RECOMMENDATION:


301.1.4 Pipe, Tubing, and Fitting Sizes. Pipe, tubing, and fitting sizes shall be expressed in nominal or standard sizes asreferenced in Table 1401.1 for material standards.

317.0 Increasers and Reducers.

Where different sizes of pipes and fittings are to be connected, the proper size increasers or reducers or reducing fittings shallbe used between the two sizes. Brass or cast-iron body cleanouts shall not be used as a reducer or adapter from cast-iron drainagepipe to metallic pipe.

gallon (1,900 L) or less capacity shall have a vent not less than one and one-quarter (1.25) inch (32 mm) nominal pipe size. [NFPA

501A: 4.4.6.4]

SUBSTANTIATION:Item # 20 should be approved as modified based on the following:1. The term “iron pipe size” is not currently used throughout the industry as the term “nominal or standard sizes”

is used for all piping, tubing and fitting sizes referenced in Table 14-1. ASTM, ASME, AWWA, CISPI and CSAstandards listed in Table 6-4 and Table 7-1 for piping and fitting material reference “nominal or standard sizes.”Iron Pipe Size was used prior to March 1927 and indicated three wall thickness [i.e. standard (STD), extra strong(XS), double extra strong (XXS)] that were in use at this time. In March 1927, the American Standards Associ-ation surveyed industry and created a system that designated wall thicknesses based on smaller steps betweensizes. The designation known as nominal or standard pipe size replaced iron pipe size, and the term schedule(SCH) was invented to specify the nominal wall thickness of pipe. By adding schedule numbers to the IPS stan-dards, today there is a range of 16 schedules, namely: SCH 5, 5S, 10, 10S, 20, 30, 40, 40S, 60, 80, 80S, 100,120, 140, 160, and STD, XS, XXS. Pipe size is specified with two non-dimensional numbers, nominal pipe size(NPS) and schedule number (SCH).

2. The term “nominal pipe size” is used by the industry as indicated by reference to the United Association InstructorTraining Program Course 251 based on the UPC as follows: “Definition for Pipe Size- See Nominal Pipe Size-

A standard expressing in inches and fractions denoting an equal, i.e., the conduit or tube is nominal pipe size

in keeping with the general dimensions of Schedule 40 pipe. Abbr. N.P.S.”



The terminology “iron pipe size” is still utilized in the field and should remain in the code.

RECOMMENDATION:


301.1 Minimum Standards.

301.1.1 Approvals. All pipe, pipe fittings, traps, fixtures, material, and devices used in a plumbing system shall be listed orlabeled (third-party certified) by a listing agency (accredited conformity assessment body) and shall conform to approved appli-cable recognized standards referenced in this code, and shall be free from defects. Plastic pipe and the fittings used for plasticpipe, other than those for gas, shall meet the requirements of NSF 14. Unless otherwise provided for in this code, all materials,fixtures, or devices used or entering into the construction of plumbing systems, or parts thereof, shall be submitted to theAuthority Having Jurisdiction for approval.



PUBLIC COMMENT:

SUBMITTER: Tim Ross, Self

RECOMMENDATION:


301.1 Minimum Standards.

301.1.1 Approvals. All pipe, pipe fittings, traps, fixtures, material, and devices used in a plumbing system shall be listed orlabeled (third-party certified) by a listing agency (accredited conformity assessment body) and shall conform to approved appli-cable recognized standards referenced in this code, and shall be free from defects.

Unless otherwise provided for in this code, all materials,fixtures, or devices used or entering into the construction of plumbing systems, or parts thereof, shall be submitted to theAuthority Having Jurisdiction for approval.

SUBSTANTIATION:

Item # 20.01 should be modified because the text “plastic pipe” is stated twice in the same sentence, and thereforeis redundant.



Current text is necessary for addressing any confusion where plastic pipe and fittings shall be listed and/or labeledin accordance with applicable standards.


VOTING RESULTS: AFFIRMATIVE: 18 ABSTENTION: 10


ADLER, AGUILAR, BERGER, MANN: I believe this to be proprietary. The first sentence reads "...and shall conformto approved applicable recognized standards referenced in this code...." To add the reference for NSF 14 is unnec-essary and proprietary.

66

FEEHAN: I disagree with the entire proposal. Listing the NSF 14 Standard is redundant and the standard doescover gas piping systems.

FISCHER: I believe the inclusion of reference standards anywhere within the Code or the appendix without includingan appropriate extract is a practice that should be avoided. This committee for the most part is not aware of changeswithin standards until after the publication of the UPC that could affect the interpretation of any UPC section, andthus the TC would be unable to correct the code if needed.

HAMILTON: Standards should not be included in the body of the code.

LEVAN: Adding the reference to NSF 14 in the general requirements is confusing. The reference should occur inChapters 6, 7, and 11 where the plastic pipe products are referenced. I also do not feel any standards related toquality control or materials standards should be added into the individual chapters but should remain in Chapter 14unless all products are given the same consideration and are added to the appropriate chapters.

RODIO: I am abstaining as I disagree with the current code change. The insertion of NSF into the code is confusingand adds nothing that benefits the end user.

TABAKH: The clarity of Chapter 14 should be revised so that there is no question that NSF 14 applies to, and onlyto, piping that serves water supply applications. It makes no sense to make a specific reference to NSF 14 for clarityregarding plastic pipe in a section referring to the listing and labeling of all piping materials in the plumbing system.

I am opposed to the original revision under Item #20.01 that was accepted by the committee. The revision specifi-cally refers to listing and labeling of plastic pipe in an area that applies to all types of piping materials for all plumbinguses. This issue needs to be addressed within Chapter 14, not by adding a specific requirement for one type ofmaterial under a code section that applies to all plumbing materials. Further, the Uponor PEX pipe samples that wehappen to have in our office indicate NSF-pw but not specifically NSF 14. Should this section be added, these pipeswould be turned down by plumbing inspectors.

RECOMMENDATION:


Delete text without substitution:

306.0 Damage to Drainage System or Public Sewer.

306.1 It shall be unlawful for any person to deposit, by any means whatsoever, into any plumbing fixture, floor drain, interceptor,sump, receptor, or device, which is connected to any drainage system, public sewer, private sewer, septic tank, or cesspool, anyashes; cinders; solids; rags; inflammable, poisonous, or explosive liquids or gases; oils; grease; or any other thing whatsoeverthat would, or could, cause damage to the drainage system or public sewer.


SUBSTANTIATION:

Section 306.1 is already addressed in Section 714.1. The purpose for Chapter 3 is to provide general regulations as theypertain to the code, and not specific code language that deals with materials, appliances, methods, or installations thatare better addressed by other sections of the code. Several sections in Chapter 3 are already present, or sufficientlyaddressed, in other sections of the UPC. For informational purposes, Section 714.1 is shown as follows: It shall beunlawful for any person to deposit, by any means whatsoever, into any plumbing fixture, floor drain, interceptor, sump,receptor, or device which is connected to any drainage system, public sewer, private sewer, septic tank, or cesspool, anyashes; cinders; solids; rags; flammable, poisonous, or explosive liquids or gases; oils; grease; and any other thing what-soever that would or could cause damage to the public sewer, private sewer, or private sewage disposal system.



The proposed deletion of Section 306.1 is a general requirement and belongs in Chapter 3.


PUBLIC COMMENT 1:

SUBMITTER: April Trafton, Donald Dickerson Associates

RECOMMENDATION:


306.0 Damage to Drainage System or Public Sewer.

306.1 It shall be unlawful for any person to deposit, by any means whatsoever, into any plumbing fixture, floor drain, interceptor,sump, receptor, or device, which is connected to any drainage system, public sewer, private sewer, septic tank, or cesspool, anyashes; cinders; solids; rags; inflammable, poisonous, or explosive liquids or gases; oils; grease; or any other thing whatsoeverthat would, or could, cause damage to the drainage system or public sewer, private sewer, or private sewage disposal system.

714.1 It shall be unlawful for any person to deposit, by any means whatsoever, into any plumbing fixture, floor drain, interceptor,sump, receptor, or device which is connected to any drainage system, public sewer, private sewer, septic tank, or cesspool, anyashes; cinders; solids; rags; flammable, poisonous, or explosive liquids or gases; oils; grease; and any other thing whatsoeverthat would or could cause damage to the public sewer, private sewer, or private sewage disposal system.

68

SUBSTANTIATION:

The TC rejected Item #25 because the committee felt that Section 306.1 belongs in Chapter 3 as a general require-ment. If that is the case, Section 714.1 should be deleted as it is a duplication of the same provisions in Section 306.1.

COMMITTEE ACTION: Reject the public comment (Failed Ballot)



NOTE: Item 25 (Public Comment 1) failed to achieve the necessary 2⁄3 affirmative vote of returned ballots. In accor-dance with Section 4-4.6.4 of the Regulations Governing Committee Projects, the TC action shall be reported in theROC as rejected.


ADLER, BERGER, MANN: This section should remain as is. This code change would eliminate the protection of thedrainage system.

AGUILAR: This section should remain as is. The original TC rejection correctly assessed the proposed code change.If passed, as modified by this comment, the Code would not protect the drainage system.

BALLANCO: Chapter 3 is for general regulations. This is a specific regulation regarding sanitary drainage. There-fore, it belongs in Chapter 7, and not Chapter 3.

BLOICE: This should remain as is due to the fact that the code already addresses the protection of the sewersystem.

CABOT: Coverage belongs in Chapter 7.

FEEHAN: This comment removes the protection of the DWV systems. Damaging products may be introduced intoDWV systems within buildings as well. This language may seem redundant, however it is necessary language forclarification.


HAMILTON: The section should remain as is. The information fits within the section title.

LEVAN: By removing "drainage system", the proposed modification would allow damaging materials to be in contactwith the drainage system.

RODIO: This section is titled “Damage to Drainage System or Public Sewer”. This code change then deletes thephrase “drainage system” from the body of the text. This section of the code should remain as is.

PUBLIC COMMENT 2:

SUBMITTER: Julius Ballanco, JB Engineering and Code Consulting, P.C.

RECOMMENDATION:


SUBSTANTIATION:

I believe that the Correlation Task Group had a valid comment regarding the deletion of this section. There is no needto repeat requirements throughout the code. The appropriate location for this text is in Chapter 7.



This public comment is being rejected in favor of Public Comment 1, which removes redundant language and keepsthe provisions within their proper location in the UPC.




BALLANCO: Chapter 3 is for general regulations. This is a specific regulation regarding sanitary drainage. There-fore, it belongs in Chapter 7, and not Chapter 3.

CABOT: Coverage belongs in Chapter 7.

SOSKIN: This section should remain as is. This code change eliminates the protection of the drainage system.

UPC 2012 – (307.0 – 307.2, 811.0, 811.1):



RECOMMENDATION:



307.0 Industrial Wastes.

307.1 Wastes detrimental to the public sewer system or detrimental to the functioning of the sewage treatment plant shall betreated and disposed of as found necessary and directed by the Authority Having Jurisdiction.

307.2 Sewage or other waste from a plumbing system that may be deleterious to surface or subsurface waters shall not bedischarged into the ground or into any waterway unless it has first been rendered safe by some acceptable form of treatment asrequired by the Authority Having Jurisdiction.


811.0 Chemical and Industrial Wastes.

811.1 Chemical or industrial liquid wastes that are likely to damage or increase maintenance costs on the sanitary sewer system,detrimentally affect sewage treatment, or contaminate surface or subsurface waters shall be pretreated to render them innocuousprior to discharge into a drainage system. Detailed plans and specifications of the pretreatment facilities shall be required by theAuthority Having Jurisdiction.

Sewage or other waste from a plumbing system that are deleterious to surface or subsurface waters shall not be dischargedinto the ground or into any waterway unless it has first been rendered safe as required by the Authority Having Jurisdiction.

Piping conveying industrial, chemical, or process wastes from their point of origin to sewer-connected pretreatment facil-ities shall be of such material and design as to adequately perform its intended function to the satisfaction of the AuthorityHaving Jurisdiction. Drainage discharge piping from pretreatment facilities or interceptors shall conform to standard drainageinstallation procedures.

Copper tube shall not be used for chemical or industrial wastes as defined in this section.

SUBSTANTIATION:

The above code revision incorporates Section 307.0 into Section 811.0. The purpose for Chapter 3 is to providegeneral regulations as they pertain to the code, and not specific code language that deals with materials, appli-ances, methods, or installations that are better addressed by other sections of the code. Several sections in Chapter3 are already present, or sufficiently addressed, in other sections of the UPC.



The proposed language added to Section 811.1 does not deal with the intent of the section which is chemical andindustrial wastes.


PUBLIC COMMENT:

SUBMITTER: Julius Ballanco, JB Engineering and Code Consulting, P.C.

RECOMMENDATION:


71

SUBSTANTIATION:

I believe that the Correlation Task Group had a valid comment regarding the deletion of this section and the place-ment of the requirements in Chapter 8. This is the more logical location for such requirements.



The provisions for industrial wastes should remain in Chapter 3 as they are considered by the TC as general regu-lations that should not be removed or added to another section of the code.




BALLANCO: Chapter 3 is for general regulations. Industrial wastes contain specific requirements. This belongs inChapter 8. The Federal Regulations identify industrial waste and chemical waste as one in the same. The UPCshould be updated to be consistent with Federal Regulations.

The other section that deals with enlargement is relocated to Item 52Section 402.6.1. The purpose for Chapter 3 is to provide general regulations as they pertain to the code, and notspecific code language that deals with materials, appliances, methods, or installations that are better addressed byother sections of the code. Several sections in Chapter 3 are already present, or sufficiently addressed, in othersections of the UPC.



The deletion of Section 311.4 removes a link to Chapter 9. The proposal eliminates the restriction on single stacksystems.

(13) A single-stack drainage and vent system with unvented branch lines.

SUBSTANTIATION:

Item # 28 should be approved as modified based on the following reasons:

1. This public comment simply places all the provisions for DWV prohibited fittings, joints, connections, and prac-tices in a list format that is more user-friendly. The provisions in Section 311.4 have been move to Sections701.5(12) and 701.5(13) within the proposal. Section 311.8 is being deleted as provisions for DWV threadedfittings are already addressed in Sections 701.2 and 705.0.

2. Since the above provisions are in regards to DWV fittings, joints, connections, and practices they should belocated within Chapter 7 versus Chapter 3.

3. The language should be revised in accordance with IAPMO’s Manual of Style that now dictates the technical andeditorial layout of all IAPMO code documents.


74


The existing language provides clear and concise language for the enforcement of prohibited fittings, joints, connec-tions, and practices. The proposed text is confusing, and such requirements should not be moved to Chapter 7 asthey are considered by the TC as general regulations that should remain in Chapter 3.




BALLANCO: This change was properly substantiated and should be approved.

TRAFTON: The change should be done per the Manual of Style.

75

78

In Section 405.0, all prohibited fixture requirements can now be found under a single section verses being spreadthroughout the UPC. Code language was relocated appropriately to under “General Requirements”. In addition, reloca-tion of the text for drinking fountains was relocated to Section 411.4, Item 30 in Correlation Task Group Report.



The proposed text creates confusion to the end user and the current text provides the intended clarification.

A PUBLIC COMMENT(S) WAS SUBMITTED FOR REVIEW AND CONSIDERATION.PUBLIC COMMENT:


RECOMMENDATION: Request to accept the code change proposal as submitted by this public comment.

SUBSTANTIATION:The argument made by the TC that this proposal creates confusion should be challenged considering nothing ofsubstance changed. The only changes involved with this code proposal were the material requirements were relo-cated into a single section within Chapter 4, and the text was formatted in accordance with the IAPMO Manual ofStyle. If anything, this proposal makes it easier for the end user to find the material requirements in regards toplumbing fixtures.



The technical committee preferred existing language that addresses material requirements in various sectionsthroughout Chapter 4 and maintains harmonization with other revisions made throughout the chapter.




BALLANCO: This change was properly substantiated and should be approved.

CABOT: The revisions are consistent with the Manual of Style and are properly substantiated.

SUBSTANTIATION:

Item # 40 should be approved as modified based on the following:

1. This code proposal places all material, water consumption, and application requirements for water closets intoa single section of code. This format will be more user-friendly for the end user than having to search throughoutChapter 4 to obtain such requirements.

2. The applicable reference standards have been added to Sections 403.1 and 403.3 to assist the end user inidentifying approved water closets and water closet seats in accordance with the UPC without having to searchthroughout Table 14-1. The importance of referencing the correct standard(s) in the body of the code providesclear and concise requirements and avoids specifying the use of proprietary materials, methods, and productsin addition to the following:

a) Standards referenced in the body of the code are to be an extension of the code requirements that increasethe level of public safety and health.

b) Standards are considered a basis for comparison and codes tell the user what to do and when and underwhat circumstances to do it.

c) Enforceable part of the code without conflicting requirements (does not leave areas open to interpretationor question).

d) A standard by itself has no legal standing of its own unless it is adopted into the code.

e) Incorporation by reference in order to eliminate error when trying to locate the appropriate referenced stan-dard that applies to a specific material or device.

f) Consistency and leveling the playing field for manufacturers.

The standard provides the performance criteria and the user does not need the standard, or even parts thereof,in order to enforce its application. All codes require that such materials be listed or labeled by a listing agencyand conform to approved recognized standards. Thereby, specifying the standard(s) in the body of the codeprovides the enforcement community, engineer, and designer the clarification needed in order to verify compli-ance.

3. References to EPA WaterSense have been removed as this is a voluntary program and therefore should not bemandated within the UPC.

4. Flush volumes less than 1.6 gallons have been removed as they are not in compliance with the performancerequirements in ASME A112.19.2/CSA B45.1 or ASME A112.19.14.






ADLER, AGUILAR, BERGER, MANN: Referenced standards should not be included in the body of the Code. Refer-enced standards are modified without public comment and any voting by IAPMO's Technical Committee.

BLOICE: The reference standards should not be in the body of the code since most plumbers don't know what theyare and what they represent.

FEEHAN: Listing the standards in the body of the code is redundant and not necessary.


HAMILTON: Standards should not be in the body of the code.

LEVAN: Adding some standards into the individual chapters is confusing and has the effect of allowing only thoseproducts which are manufactured to the standards in that section when other products which are found in Chapter14 would be excluded. This adds confusion and places the burden on each manufacturer or seller of a product tohave their standard in every chapter of the code. This creates a barrier to use of products which are manufacturedto standards which are acceptable but not found in the individual chapters. Until all product standards for eachchapter are added none should be added to the individual chapters.

RODIO: The insertion of standards into the body of the code should be limited to very rare instances. The standardsare properly referenced in Chapter 14. The insertion of the standards into the body of the code allows them to bemodified with no input from IAPMO or even a review. As the standard bodies modify the standards the changes areautomatically incorporated into our code as the listed standards have no reference dates. The argument that Chapter14 has the dates does not stand if Chapter 14 is not adopted by the AHJ. Also the standards are confusing to thebasic users of the code (plumbers and inspectors). Plumbers and inspectors do not carry around thousands ofdollars worth of standards that are constantly being updated and modified. The standards are mainly for the benefitof the manufacturers. The listing process and Chapter 14 is where the standards should be referenced and utilized.

82

83

SOSKIN: Referenced standards should be included in Chapter 14 not in the body of the code.

TABAKH: I am fundamentally opposed to identifying the specific standards for each material and each fixture withinthe body of the code. The code needs to remain clear and concise. Listing the specific standards within the body ofcode for each material or fixture is redundant. These standards are already listed in Chapter 14.

Having a phrase referring the reader to Table 1401.1 at every code section for each individual plumbing fixtureis a waste of space in the code. This phrase already appears in Section 401.1 as a general requirement to apply forall fixtures. It does not need to be repeated throughout the code.

Changes need to be made to Chapter 14 so that it is easier to look up the standards associated with materialsand products. Having the standards in alphabetical and numeric order is of very little use to an engineer trying to specout fixtures and materials or to an inspector trying to verify that an installation meets the code. The people who usethe code on a daily basis are concerned with finding acceptable fixtures and materials, not in finding individual stan-dards. We don’t select materials by reading down an alphabetical list of standards. Chapter 14 needs an alphabet-ical list of materials and fixtures.

A table in Chapter 14 needs to be added to show each separate material and fixture in its own category with acomplete list of all the standards that apply to that specific material or fixture. This will allow a designer to quicklydetermine acceptable materials for the job. This will reduce the time and difficulty associated with inspecting plumbinginstallations because all the standards associated with each type of fixture will be contained in one place and in oneChapter rather than throughout the entire code book.

PUBLIC COMMENT 2:

SUBMITTER: Thomas Pape, Alliance For Water Efficiency

RECOMMENDATION:


SUBSTANTIATION:

The TC statement for rejection was: “The proposed text is in conflict with 1.6 GPF Federal regulations for waterconsumption.” This is an incorrect statement; the Federal preemption has expired and DOE has issued Docket No.EERE–2010–BT–STD–WAV–0045 to verify such. The TC needs to re-evaluate this proposal to either accept, orreject with valid substantiation to establish an accurate record for its decision on this proposal.



This public comment is being rejected in favor of Public Comment 1 which is based on federal requirements andprovides clarification for enforcement.






UPC 2012 – (402.3, 402.3.1, 409.0, Table 4-1):


RECOMMENDATION:



402.3 Urinals. Urinals shall have an average water consumption of a maximum of 1 gallon (3.8 liters) of water per flush.

Footnote 10 (from Table 4-1)

General. In applying this schedule of facilities, consideration shall be given to the accessibility of the fixtures. Conformitypurely on a numerical basis may not result in an installation suited to the needs of the individual establishment. For example,schools should be provided with toilet facilities on each floor having classrooms.

a. Surrounding materials, wall, and floor space to a point two (2) feet (610 mm) in front of urinal lip and four (4) feet(1,219 mm) above the floor, and not less than two (2) feet (610 mm) to each side of the urinal shall be lined with non-absorbent materials.

404.6 Floor and Wall Materials. Surrounding material, wall and floor space to a point 2 feet (610 mm) in front of urinal and4 feet (1219 mm) above the floor, and not less than 2 feet (610 mm) to each side of the urinal shall be lined with nonabsorbentmaterials.

SUBSTANTIATION:

The new code language in Section 404.1 makes it clear that the intent of the UPC is to only permit products that arelisted and labeled per approved standards in Table 1401.1. Section 404.2 is based on the IAPMO Green Plumbingand Mechanical Code Supplement.

84

The purpose for the above code revision is to reorganize the footnotes, and footnotes from Table 4-1 into a moreuser-friendly format. The user can now find all of the application, water consumption, backflow, and material require-ments for a fixture in the same section verses spread throughout the UPC. No revision to the intent of the originalcode language.

Section 404.3 incorporates language from the IAPMO Green Plumbing and Mechanical Code Supplement.



The proposed text is in conflict with Federal regulations of 1.0 GPF for water consumption. “Schedule of facilities”is currently not defined in the code.


PUBLIC COMMENT 1:


RECOMMENDATION:


402.3 Urinals. Urinals shall have an average water consumption of a maximum of 1 gallon (3.8 liters) of water per flush.

404.0 Urinals.

Nonwater urinals shall permit the uninhibited flow of wastethrough the urinal to the sanitary drainage system. Nonwater urinals shall be cleaned and maintained in accordance with themanufacturer’s instructions after installation. Where nonwater urinals are installed they shall have a water distribution lineroughed in to the urinal location at not less than 56 inches (1422 mm) to allow for the installation of an approved backflowprevention device in the event of a retrofit. Such water distribution line shall be provided with a shutoff valve located as closeas possible to the distribution main to prevent the creation of dead ends. Where nonwater urinals are installed, not less than onewater supplied fixture rated at not less than 1 water supply fixture unit (wsfu) shall be installed upstream on the same drain lineto facilitate drain line flow and rinsing.

Footnote 5 (from Table 4-1) 404.4 Substitution. For each urinal added in excess of the minimum required, one water closetshall be permitted to be deducted. The number of water closets shall not be reduced to less than two-thirds (2/3) of the minimumrequirement.

409.0 Urinals. 404.5 Backflow Protection. Every The water supply to a urinal shall be protected by an approved-typevacuum breaker or other approved backflow prevention device as described in accordance with Section 603.4.

SUBSTANTIATION:


1. This code proposal places all material, water consumption, backflow protection, and application requirementsfor urinals into a single section of code. This format will be more user-friendly for the end user than having tosearch throughout Chapter 4 to obtain such requirements.

85

2. The applicable reference standards have been added to Section 404.1 to assist the end user in identifyingapproved urinals in accordance with the UPC without having to search throughout Table 14-1. The importanceof referencing the correct standard(s) in the body of the code provides clear and concise requirements andavoids specifying the use of proprietary materials, methods, and products in addition to the following:









4. Flush volumes less than 1.0 gallons have been removed as they are not in compliance with the performancerequirements in ASME A112.19.2/CSA B45.1 or IAPMO Z124.9.

5. Based on the actions of the TC in approving Item #62 (New Table 4-1), footnotes 5 and 10(a) should be relo-cated within this proposal since the footnotes pertain to urinals (refer to Sections 404.4 and 404.6).






ADLER, AGUILAR, BERGER, MANN: Referenced standards should not be included in the body of the Code. TheseReferenced standards are modified without public comment and any voting by IAPMO's Technical Committee.

PUBLIC COMMENT 2:


RECOMMENDATION:


SUBSTANTIATION:

The TC statement for rejection was “The proposed text is in conflict with Federal regulations of 1.0 GPF for waterconsumption. ‘Schedule of facilities’ is currently not defined in the code.” The Federal pre-emption on these prod-ucts has expired and DOE has issued Docket No. EERE–2010–BT–STD–WAV–0045 to verify such. The term“schedule of facilities” already exists in the UPC 2009; this proposal does not introduce a term that is not already inuse. The TC needs to re-evaluate this proposal to either accept, or provide more valid statements for rejection toestablish an accurate record for its decision on this proposal.

SUBSTANTIATION:

The new code language in the first sentence of Section 405.1 makes it clear that the intent of the UPC is to onlypermit products that are listed and labeled per approved standards in Table 1401.1. The second sentence has notbeen revised from the intent of the original code language and has been relocated into the appropriate section. Foot-note 8 from Table 14-1 have been reorganized into a more user-friendly format.

89

The proposed new text in Section 405.2 is based on the IAPMO Green Plumbing and Mechanical Code Supplement.

In Section 405.4, continuous waste and fixture tailpiece provisions are now provided for each appropriate fixture.

In Section 405.5, overflow provisions are now included for each appropriate fixture. The purpose for the above coderevisions reorganizes the fixtures from Table 4-1 into a more user-friendly format. The user can now find all of theapplication, water consumption, backflow, and material requirements for a fixture in the same section verses spreadthroughout the UPC.



The proposed text in Section 405.2.1 is more restrictive than current federal regulations. EPA WaterSense is a volun-tary program and therefore not mandated by the code.
