When should I add salt to my brine tank?

The salt in your brine tank will eventually be dissolved entirely in water used to regenerate the resin in your softener. Salt must be added whenever the water level in the brine tank is higher than the salt level as the brine tank is designed to be filled to the top.

An 18" x 33" brine tank can hold 300 lbs. of salt.

An 18" x 40" brine tank can hold 400 lbs. of salt.

A cabinet style water softener can hold 250 lbs. of salt.
