How long does a water softener last?
Typical lifeAbout 15 yearspublished estimates
Range10–25 yearstype and upkeep
A water softener typically lasts about 15 years. Published estimates run from 10 to 25 years, depending on type, use and upkeep.
What shortens it
- Chlorine and chloramine breaking down the resin
- Iron fouling the resin
- Very hard water, which means more regenerations
- Skipped maintenance and salt bridges
When it starts to fail
Hard water comes back, salt use changes, or the valve starts running at the wrong times. Check repair prices, or decide whether to repair or replace.
