Fixing a Softener That's Stopped Softening
Spots are back, the soap won't lather, or the brine tank is full of water. On Rochester water, a failing softener shows up fast.
Water softener repair typically costs $162–$985, averaging about $559 (HomeAdvisor). Common fixes include a stuck control valve, a clogged injector, a salt bridge, worn seals or exhausted resin. Softeners last roughly 10 to 15 years, so an older unit with a failing tank is often better replaced.
Signs it's failing
- Scale and spots return on glass and fixtures.
- Salt level in the brine tank hasn't dropped in weeks.
- Standing water in the brine tank.
- The unit regenerates at odd times or constantly.
- Water pressure falls when the softener is in service.
At 17 grains per gallon (RPU), the difference between soft and hard water is obvious, so these signs don't stay hidden for long.
Common fixes
Salt bridges form when salt crusts over and water can't reach it; breaking the crust often restores regeneration. Injectors and screens clog with sediment and stop the unit drawing brine. Control valves wear, lose their settings or stall on a failed motor. Resin eventually loses capacity and can be replaced without a new tank. HomeAdvisor puts labor at $45 to $150 an hour, typically one to three hours, and a new brine tank at $125 to $700.
Iron, polyphosphate and resin
RPU adds a blended polyphosphate at about 0.5 ppm, partly to control corrosion and partly to keep the iron that occurs naturally in its well water stable (RPU). Iron that does reach a softener can gradually coat the resin beads and cut their capacity. If your softener seems to lose ground year after year rather than failing all at once, a resin cleaning or a resin replacement may bring it back without buying a new unit.
Replace instead?
If the unit is past 15 years, the resin tank leaks, or parts for the valve are no longer made, a new softener is usually better value. A replacement is also a chance to move from a timer valve to a demand-based one, which the MPCA says uses salt more efficiently. The Rochester water softener price guide compares repair and replacement ranges.
Licensing covers service too
Minnesota's water conditioning law covers servicing as well as installation (Minn. Stat. 326B.50 and 326B.55). Whoever works on your softener should be a licensed plumber or water conditioning journeyworker or master, under a water conditioning contractor's license, unless you're doing the work yourself on the home you own and live in.
Questions homeowners ask
What can I check before calling?
Make sure the bypass valve is in service, the unit has power, the clock or settings are right, and the brine tank has salt that isn't crusted. Those four cover a lot of service calls.
Why is there standing water in my brine tank?
Usually the unit isn't drawing brine during regeneration. A clogged injector, a kinked brine line or a stuck float are the common causes, and all are routine repairs.
