action allows the
motor to
turn the rotor and disc into
BRINING position. Water flow is directed to the nozzle. Suction, created by the
nozzle and venturi, draws brine from the salt storage tank and injects it into the resin
bed via the bottom distributor. Flow continues out the top distributor and to the
drain. Hard water is available at the valve outlet.
When the brine valve closes to end brine draw, water flow continues in the same
directions to slowly RINSE brine from the resin bed and to the drain.

Timer/switch action again allows the motor to turn the
rotor & disc to place the valve in BACKWASH, stopping
water flow to the nozzle. Water is routed down and out
the bottom distributor, up through the bed, and out the
top distributor to the drain. The fast flow (controlled by
a flow plug in the drain fitting) flushes dirt, sediments,
iron deposits, remaining brine and hardness to the
drain.
