Valve Drain Requirements - Whirlpool WHES20 Installation And Operation Manual

Valve Drain Requirements
Use the flexible green 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 &ain hose runs, or elevating the hose more than 8' above the floor. Make the
water softener valve drain as short and direct as possible.
