5E. WATER FLOW THROUGH THE SOFTENER VALVE
SERVICE CYCLE
Hard water enters the valve inlet port. Internal valve porting routes the water down and
out the top distributor, into the resin tank. Hard water is softened as it passes through the
resin bed, then enters the bottom distributor. Soft water flows back into the valve and out
the valve outlet, to the house soft water pipes.

FILL CYCLE
To begin a regeneration, the solid state timer energizes the circuit to the valve motor. The
valve motor rotates the rotor and disc and the valve cam until the position switch lever drops
to open the motor circuit and position the valve in FILL. As the rotor and disc rotates, the
port opens for SOFT water fill through the venturi. Fill flow continues to the brine valve,and
into the salt storage tank. Soft water is still available to the house lines.
