Installation Requirements
VALVE DRAIN REQUIREMENTS
Using the flexible drain hose (included), measure and cut to the length needed. Flexible drain hose is not allowed in all localities (check your plumbing codes). If local codes do not allow use of a flexible drain hose, a rigid valve drain run must be used. Purchase a com- pression fitting (1/4 NPT x 1/2 in. minimum tube) and 1/2" tubing from your local hardware store. Plumb a rigid drain as needed (See Figure 6).
NOTE: Avoid drain hose runs longer than 30 feet. Avoid elevating the hose more than 8 feet above the floor. Make the valve drain line as short and direct as possible.
INLET / OUTLET PLUMBING OPTIONS
Always install either a single bypass valve (provided), as shown in Figure 7, or, if desired, parts for a 3 valve bypass system (not included) can be purchased and assembled, as shown in Figure 8. Bypass valves allow you to turn off water to the softener for mainte- nance if needed, but still have water in house pipes. Pipe fittings must be 3/4” minimum.
Use:
=Copper pipe
=Threaded pipe
=PEX (Crosslinked Polyethylene) pipe
=CPVC plastic pipe
=Other pipe approved for use with potable water
IMPORTANT: Do not solder with plumbing attached to installation adaptors and single bypass valve. Soldering heat will damage the adaptors and valve.
