How long do water softeners last?
Most water softeners last 10 to 15 years. Water softeners are commonly given about 10 to 15 years; the resin bed is the part that wears out.
A softener protects other appliances from scale, so its condition affects the life of your water heater, dishwasher and washer. The upkeep is mostly salt and the occasional clean.

Water softener maintenance checklist by season
Spring
Check the salt level and break up any hard crust, called a salt bridge, if the salt looks packed with an empty gap below. Check the drain line for leaks.
Summer
Test the water hardness with a test kit. If it is not soft, the unit may need service or a different regeneration setting.
Fall
Clean the brine tank if it has sludge and use clean salt of the type your maker lists. Check the bypass valve moves freely.
Winter
Keep the unit and the drain line from freezing. Check the settings after a power outage, since the clock and regeneration schedule may reset.
Signs your water softener needs replacing
- Soap does not lather well and spots return on glass and fixtures.
- Hardness test shows hard water even after regeneration.
- Salt usage is far higher or lower than usual.
- Leaks at the valve or tank, or a resin smell or discolored water.
- The unit is past roughly 10 to 15 years.
Typical water softener warranty
Warranties are often several years on the valve and electronics and a long term, sometimes ten years or more, on the tanks. Resin coverage varies. Terms differ by brand.
An appliance warranty tracker keeps your water softener's coverage dates and receipt in one place.
What to keep for a water softener

- Model and serial number from the control head or tank label

Common questions
How long do water softeners last?

How often should I add salt?
Check the brine tank every month or so and keep it at least a quarter full or per your manual. Usage depends on hardness and water use.
Does a water softener help my appliances last longer?
Hard water leaves scale in water heaters, dishwashers and washers, which can reduce efficiency over time. Softening reduces this, though your appliance manuals set their own water guidance.
How do I maintain a water softener?
Follow your manual first. Each season: spring, check the salt level and break up any hard crust, called a salt bridge, if the salt looks packed with an empty gap below. Check the drain line for leaks. Fall, clean the brine tank if it has sludge and use clean salt of the type your maker lists. Check the bypass valve moves freely.
