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.

To begin a regeneration, the electronic 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 vane, and into the salt storage
tank. Soft water is still available to the house lines.
