Valve Drain Requirements

Use the flexible drain hose, that is 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. Buy a compression fitting (1/4 NPT x 1/2 in. minimum

tube) and 1/2” tubing from your local hardware store. Then plumb a rigid drain as needed (see Figure

3).

NOTE:

Avoid long drain hose runs, or elevating the hose more than 8’ above the floor. Make the

water softener valve drain as short and direct as possible.
