Water Softener - Float Position

We are sometimes asked if the float in a water softener has a specific required position. This article explains the design and operation of the float.

Understanding the Position of the Float In a Water Softener

The float moves up and down the stem, it floats in the water and has no set point. There is a "Stop" at the top that is used as a safety shut off in case the valve malfunctions. The position of this "Stop" is approximately 2.5" to 3" from the top of the Stand Tube. If the valve malfunctions, the float raises, the stem and the water going into the brine tank will shut off, avoiding a tank overflow.
