1) LOCATE DRAIN PORT ON THE LEFT (OUTLET) SIDE OF THE VALVE HEAD.
• Inserted into drain port is a flow control housing. The flow control housing (male o-ringed insert x 1/2”FNPT) is a plastic disc,
held in by a retainer clip. The flow control housing has a flow washer which determines the flow rate in gpm from drain line.
2) DO NOT OVERTIGTHEN CONNECTIONS. IMPORTANT TO READ THE FOLLOWING:
• Nominal drain line and drain size should be a minimum of 1/2”. **Backwash flow rates of 7 GPM (1354 units) with drain line
exceeding 20’ in length require 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. A drain adapter or hose barb has been supplied and is only
loosely connected. You may use this or any other applicable adaptor or connector depending on your drain line.
• 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 backwash water must be available. Usually, into a drain or trap, or outside that has sufficient
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.

1) IDENTIFY THE MAIN WATER SUPPLY.
• Do Not Assume. You may have to perform “the old bucket test” to determine where the water is coming from.
• Make sure the whole facility is on the line. Some cold water lines (kitchen, island, wet bar sinks, refrigerators, ice-makers)
may have been plumbed separately, if previously plumbed for softened (salts) water. You may have to recapture those
lines by replumbing that manifold. Or, capture the main water supply before the bypassed or “looped” away lines, usually
found at, or after, the main water shut off. However, some plumbing designs prevent this ideal installation. A sink (point of
use) filtration unit can be used for that missed location.
• 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) connected 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.
Note: If, recirculating pump on water heater, unplug pump before turning off water supply. Prevents damage to the pump motor.
