The answer to 'how long does water softener last' is that a typical water softener lasts 10-15 years with proper maintenance and care. The lifespan of a water softener can vary depending on factors like water hardness, usage, and the quality of the softener itself. Proper maintenance, including regular salt refills and occasional resin bed cleaning, can help extend the life of a water softener.
Over time, the resin beads inside the softener tank will become depleted and less effective at removing minerals from the water. Signs that a water softener needs to be replaced include reduced water softening performance, increased salt usage, or an older unit that is more than 15 years old. When it's time to replace the softener, it's best to consult a professional plumber to ensure the new unit is properly sized and installed for your home's water needs.
