Owner's Manual

Never make a direct connection into a waste water drain. A physical air gap of at least 3
inches (76 mm) between the end of the drain line and the wastewater level in the drain pipe
should be used to avoid contamination of the line. An additional gap of 3/4 inch (19 mm)
between the drain pipe and drain line is recommended to prevent any problems in the case of
a pipe overflow. Using a simple P-trap as shown——is ideal as well, but a stand pipe with a
diameter of at least 1.5 inches (38 mm) is adequate. As the water coming out is under
pressure, make sure to secure the drain line so that it does not move and create a mess.
Do not tie multiple systems into a single drain line.
If hooking up multiple systems, each system needs a separate, independent drain line to
ensure proper operation and prevent damage. Systems can all be run to the same
standpipe/sump/outside drain, but the drain line from each system needs to be separate.
Do not use additional fittings on the drain line.
Avoid installing any additional fittings (check valves, ball/gate valves, etc.) as this can prevent
proper backwash and cause premature system failure.
1. Inlet/Outlet Connections
Do not overtighten the screws. The bypass valve will have some up and down movement,
this is normal. The clips simply hold the connection fittings together and the screws only need
tightened enough to keep the clips in place. Further tightening will not stop leaks and
tightening too much can damage the system, which will not be covered under warranty.
