1) LOCATE DRAIN PORT ON THE LEFT (OUTLET) SIDE OF THE VALVE HEAD.
Inserted into valve drain port is a flow control housing (male o-ringed insert x 1/2” FNPT) which is locked in by the retainer clip
The flow control housing has a flow washer which determines the restricted flow rate (4 gpm - 1035 and 1054, 7 gpm - 1354).
2) DO NOT OVERTIGTHEN CONNECTIONS. IMPORTANT TO READ THE FOLLOWING:
Nominal drain line and drain size should be a minimum of 1/2”. Drain line exceeding 20’ in length and/or drain water that is
expected to flow over 5’ above the height of the drain port requires a 3/4” line and drain. Install, non-restrictive, check valve in
drain line, if drain water is expected to flow over 5’ above the height of the drain port . Never restrict the backwash drain
water flow.
A drain adapter or hose barb has been supplied and is loosely connected awaiting final installation. You may use this or
any other applicable adaptor or connector depending on your drain line.Care must be taken when screwing in any connection to
the flow control housing, not to crush piece and distort the flow washer, crucial to the effective backwashing of the system.
Flexible tubing, poly tubing or any hose must be clamped (do not overtighten) and do not allow any tubing to kink.
Hard piping of drain line: NO Heat, NO Torch, leave at least 12” between drain port and any solder joints - remember to
use a union (a quick disconnect feature) for future servicing applications. Therefore, the system will require no replumbing.
Teflon tape is the only sealant to be used on any drain fitting.
3) LOCATE A SUITABLE PLACE TO DRAIN.
A suitable place to drain the water must be available. Usually, into a drain or trap, where the washer drains, the pool, or
any outside that has sufficient size and space for percolation. You can be flexible or creative. Do not connect the backwash line
to an air conditioning drain line. Do not freeze.
Air gap must be used, if connecting to a drain line or sewer trap, to prevent possible back siphoning into the tank.
Backwash is a mechanical way of turning over the filtration media. The discharge is only water and not a brine. The water
discharge can go anywhere, may be used, or recycled, and does not have the legal restrictions or issues of brine discharge.

Hose bibs are unnecessary to capture unless required by consumer. Irrigation (which should tee-off prior to the home’s
main water supply) uses a lot of water and this connection should be discouraged. It puts an unnecessary burden on the
unit and the media.
2) USING THE CONNECTED BYPASS VALVE AND 1” MALE NPT YOKE.
3) PLUMB INLET (supply) AND OUTLET (filtered) INTO THE UNIT.
Follow the directional arrows molded onto the valve body and bypass. See pictures below for; top/front/back and left/
right views to prevent plumbing the unit backwards. Teflon tape is the only sealant to used on any of our fittings.
NO Heat, No Torch; Leave at least 12” between the male yoke and any solder joints. Failure to do this could cause
interior damage. Consider flexible stainless (1”FNPT x 1”FNPT (3/4” if your application) and at least 18” in length) con-
nected to copper male adapters, or some other applicable connection - no heat, saves time, neat install, if applicable
code to your application.
4) WARNING: ONCE PLUMBED,
DO NOT TURN ON WATER, UNTIL YOU BEGIN START-UP PROCEDURES.
