WATER FLOW THROUGH THE SOFTENER VALVE
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.

FAST RINSE CYCLE
FAST RINSE CYCLE
During FAST RINSE, the rotor & disc is positioned
so water flow enters the resin tank through the top
distributor, and exits through the bottom distributor,
to the drain.
The electronic timer again energizes the motor to
return the valve to service. As the valve rotates,
the position switch lever drops to open the circuit.
The valve remains positioned in service until the
electronic timer initiates the next regeneration.
