Tap and Well

Water softeners

A salt-based softener installs where water enters the house. It exchanges hardness minerals for sodium or potassium.

Treasure Valley city water is often at or above 7 grains per gallon, the line where a softener is worth considering for scale and soap use. Hardness is not a federal health violation. A softener does not remove arsenic, nitrate, or fluoride.
