Softener Maintenance

Most softener problems come down to salt, settings or a blocked brine tank. This section covers how much salt a softener uses, which salt to buy, the hardness number to enter, how often it should regenerate, and step-by-step fixes when it stops using salt or the water turns hard again.

Where settings depend on your model, we point you to the manufacturer’s manual rather than guessing.
