Softener regenerates at the wrong time (often after a power outage)

Most timer and metered controls schedule regeneration by the clock, typically in the middle of the night. After an outage the clock can be wrong or reset, so regenerations happen when people are using water. The softener still softens, but the clock and settings need checking.

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.

Low water pressure after the softener

Pressure loss across a softener usually comes from a clogged pre-filter, fouled or broken-down resin, resin escaping into lines, or a valve stuck partly in a regeneration position. Bypassing the unit isolates it quickly.
