Interpreting the Cam Positions

Located under the top cover, the valve head on your softener houses a rotating metal cam.

The cam spins during a recharge cycle to route water through different paths within the system. The top of the cam is printed with letters to signify the different recharge stage positions:

S - Service (Normal flow, not recharging)

F - Fill (1st stage of recharge)

Br - Brine (2nd stage of recharge)

Bk - Backwash (3rd stage of recharge)

R - Rinse (4th and final stage of recharge)
