What is PEX
• PEX was developed in the 1960’s
in Germany and has been used in
plumbing applications for over 30
years in Europe
• Through one of three processes,
©
10Friday, September 20, 2013
• Through one of three processes,
High Density Polyethylene
undergoes a change to produce a
three dimensional link.
• This makes PEX stable for higher
temperature applications such as
plumbing and radiant heating.

The amended definition of “lead free” is provided
• 0.20% max lead for solder and flux
• 0.25% max lead for products by weighted average
• Multiple component products are calculated to address total
wetted exposure based upon wetted surface area of each
component and that component’s lead content by percentage

PEX Tubing Installation Practices
Water Heaters and Other Heat Sources
• DO NOT connect directly to gas fired hot water heater
• Check With Local Codes Regarding Connecting To Gas Water Heaters
©
19Friday, September 20, 2013
Maintain a minimum of
6 inches of clearance
from gas heater vents
Minimum of 12 inches of vertical heat sources like
recessed lights and appliance or heater vents
PEX Tubing Installation Practices
Concrete Installation
• Use plastic elbow sleeves when exiting slab
• Protect tubing via sleeving
when passing through
expansion joints
©
20Friday, September 20, 2013
• Fasten tubing every 2-3 feet to
wire mesh
• Protect the PEX tubing with
non-metallic sleeving material
where it enters and/or exits a
slab. (PEX need not be
sleeved its entire length.)
Water Hammer, Grounding, Pressure Testing
Water Hammer
• PEX tubing reduces the tendency for water hammers, and
helps prevent damage that might be caused by these
pressure changes.
• Arrestors are still advisable in situations where rapid flow
stoppage may occur or when required by code
Grounding
©
21Friday, September 20, 2013
Grounding
• Neither PEX nor aluminum PEX products may be used as
electrical ground
Pressure Testing
• The system must be pressure tested in accordance with
local codes or at least at working pressure (within tubing
limits)

How Does The Home Run System Work?
• It’s uses a centrally located
manifold with individual
shut-off valves to supply
each fixture with dedicated
distribution lines.
• PEX distribution lines run to
©
37Friday, September 20, 2013
• PEX distribution lines run to
each fixture in a “home-run”
system.
• A large reservoir in each
side of the manifold helps
maintain equal pressure
• Appropriately-sized lines can be installed so hot water is delivered faster. (3/8” and 1/2”)
• Less water is wasted while purging
How Does the Home Run System Work?
©
38Friday, September 20, 2013
• Less water is wasted while purging these lines.
• Reduce water and energy waste by up to 40%
• By providing each fixture with its own distribution line, the system out-performs conventional plumbing designs.
