In regions with sandy soils meeting the requirements noted and where the subgrade elevation is above the groundwater table, imported base materials maynotbeneeded.(Formoreinformationseespecificationsection2.03A.)

Standing water in the excavation will prevent proper base preparation and mustberemoved,ifpresent.

Installbasematerials.Basematerialsmustmeetspecsection2.03A.

For all units larger than a Single R-Tank®, you will need to disassemble the R-Tank®inordertocuttheinteriorplates.ReassembletheR-Tank® when cutting is completed, and replace the R-Tank®intotheproperlocation.

Install the pipe into the R-Tank®unit.

Seal the opening on top of the pipe with a cap or temporary lid to prevent debrisfromenteringthesystem.

Maintenance Ports:Typicallymadefrom12”Schedule40PVCpipe(checkplansforactualsizeand type of pipe), cut the pipe to length, leaving enough excess to trim the topwhenfinalgradeisreached.

Using your reciprocating saw, cut several 8” triangular notches into the bottomofthepipeasshownonplans(Fig.14).Drillseveralairventsintothe pipe just below where the top of the R-Tank® will be once the pipe is installedintothetank.

IMPORTANT: Do not over-cut the R-Tank®plates.Minimizethe gaps between the pipe and the R-Tank®plates. Thisisparticularlyimportantwiththetopplate.

TIP: If using Prefabricated Pipe Boot Kits, install them onto the pipe now, leaving the band clamps loose so that finaladjustmentsmaybemadeinStep7.

TIP: If the location of Maintenance Ports is not shown on your plans,includeaportwithin10’ofallinletandoutletpipes (a single Maintenance Port can cover multiple pipe connections), and include additional Maintenance Ports as needed to prevent the distance between ports fromexceeding50feet.
