How long does a water softener last?
A water softener lasts about 10 to 15 years. Enter the install year and this calculator estimates the life remaining and when to plan a replacement, so you keep protecting your pipes, water heater, and fixtures from hard-water scale.
Keeping the brine tank stocked with salt and cleaning it occasionally helps the unit last. If your water starts feeling hard again, you see spotting on glassware, or the resin is years old, it may be time for a new softener.
These lifespans are typical ranges for a well-maintained unit. Hard water, heavy use, and skipped maintenance shorten them; regular service extends them. Use the estimate to plan a replacement fund, not as a firm expiration date.
