The answer to 'how long does water softener last' is that a typical water softener can last 10-15 years with proper maintenance and care. Water softeners use an ion exchange process to remove minerals from hard water, and over time the resin beads that facilitate this process can become depleted or fouled. Regular maintenance, including periodic cleaning and recharging of the resin, can help extend the lifespan of a water softener.
The actual lifespan of a water softener can vary depending on factors like water hardness, frequency of use, and the quality of the unit. Softeners in homes with very hard water or high water usage may need to be replaced more frequently, while those in homes with moderate water hardness can potentially last 15 years or more. Regularly checking the softener's performance and maintaining it according to the manufacturer's recommendations is key to maximizing its longevity.
