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 slowly 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.
