Plumb arigid drain as needed (See Figure 6).NOTE: Avoid drain hose runs longer than 30 feet.Avoid elevating the hose more than 8 feetabove the floor. Make the valve drain line asshort and direct as possible.INLET / OUTLET PLUMBING OPTIONSAlways install either a single bypass valve (provided),as shown in Figure 7, or, if desired, parts for a 3 valvebypass system (not included) can be purchased andassembled, as shown in Figure 8. Bypass valvesallow 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 waterIMPORTANT: Do not solder with plumbing attached toinstallation adaptors and single bypassvalve.
