The answer to 'water softener replacement frequency' is that the typical lifespan of a water softener is 10-15 years with proper maintenance. Water softeners gradually lose their ability to effectively remove minerals from your water over time, so it's important to replace them when they become less effective. Factors like water hardness, usage, and maintenance will impact the exact replacement timeline for your home.
Regular maintenance, such as adding salt and cleaning the resin bed, can help extend the life of your water softener. However, even with diligent upkeep, you'll likely need to replace the entire unit after 10-15 years of use. Paying attention to signs of declining performance, like less effective water softening or more frequent regeneration cycles, can help you determine when it's time to install a new water softener.
