Valve Drain Requirements
Using the flexible drain hose (included), measure and
cut to the length needed. Flexible drain hose is not
a
llowed 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.
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
the single bypass valve. Soldering heat
will damage the plastic valve.
