Valve Drain Requirements

10
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.
