1) LOCATE DRAIN PORT ON THE SIDE OF THE VALVE HEAD.
Screwed onto the valve drain port is a brass flow control housing which has a flow washer which determines the restricted flow
rate of 7 gpm.
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.
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.
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) PLUMB INLET (supply) AND OUTLET (filtered) INTO THE UNIT AND PLUMB BYPASS VALVE BETWEEN.
Follow the directional arrows molded onto the valve body. See schematic for proper installation to prevent any misunder-
standing and to prevent plumbing the unit backwards.
Teflon tape is the only sealant to used on any of our fittings.
See schematic for proper bypass set-up
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 and at least 24” in length) connected to copper male
adapters, or some other applicable connection - no heat, saves time, neat install, if applicable code to your application.
3) WARNING: ONCE PLUMBED,
DO NOT TURN ON WATER, UNTIL YOU BEGIN START-UP PROCEDURES.
