6. Locate water line or pipe to be cut and make sure of direction of water flow.
CAUTION: do not cross-connect or plumb backwards. Make sure of the direction of water flow from cut pipe to
be connected.
7. Plumb Inlet and Outlet Connections to and from the system.
ReQUIReD: Use stainless steel corrugated flexible water connectors, PEX or PvC Sch 40 unless restricted
by local plumbing code.
wARNING:
be sure the incoming water supply is connected to the inlet port of the valve.
note: the valve and bypass are marked with arrows indicating the proper flow direction.

Stainless steel corrugated flexible water connectors, PEX or PvC Sch 40 have a flexible capability that will assist with the
installation where the rough plumbing and finish measurements are slightly off.
wARNING: do not force valve and bypass to meet the plumbing. this will cause stress between tank neck and valve
connections which will result in leak issues under pressure.
wARNING: do not use pipe joint compound or pipe dope. Use teflon tape only on all external pipe threads.
CAUTION: Allow for a gentle curve when using flexible connections to avoid a rigid connection. Support inlet and
outlet plumbing in some manner (use pipe hangers) to keep the weight off of the valve fittings.
CAUTION: An operating and maintained pressure reducing valve (Prv) may be required on the main water line and
prior to the system to regualte pressure. If applicable, a check valve on the main supply before the system
or a check valve on the outlet side of the the system (water heater will require expansion tank) to prevent
backflow and excessive head pressure may be required. location of system on the lowest or highest floor
or where home is located at the bottom or top of a hill may create head pressure or pressure variances.
wARNING: Any pressure on the system exceeding, surging or spiking above 75 psi and any negative pressure
due to vacuum break voids the warranty.
wARNING: If making a soldered copper installation, do all sweat soldering before connecting pipes to the
