How long should a water softener last?

A quality water softener commonly lasts 10 to 15 years and may operate longer when it is properly sized and maintained. Lifespan depends on the equipment, source-water chemistry, water use, salt quality, installation, and service history.

Iron, sediment, chlorine, and other substances can shorten the life of internal components or resin. Routine service helps catch developing problems before they result in system failure.
