Softener not regenerating

A softener that never regenerates usually has a drive problem (motor, gears, stuck piston), a programming problem, or a meter that is not counting. Error codes on Fleck and Clack valves point straight to the drive.

Brine tank overflowing or holding too much water

Excess brine water means the valve refills but does not draw brine out, or the refill does not stop. Typical causes are a plugged injector or screen, a kinked or scaled brine line, a stuck float, or internal valve leakage.

Hard water returning (softener has salt but water is hard)

Most hard-water callbacks come from salt that is not reaching the water (bridge or mush), wrong settings, or a regeneration that is not drawing brine. Check the brine tank first, then programming, then the valve.
