5C. WATER FLOW THROUGH THE SOFTENER VALVE

BRINING AND BRINE RINSE CYCLES

After fill, timer/switch 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 slowlv RINSE brine from the resin bed and to the drain.

BACKWASH CYCLE

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.
