Water Expert Andy Ball: How much salt should my softener use?

1. An average softener with 1 cu. ft. of resins (30,000 grain, 10 ” x 44 ” tank) should use about 6-8 lbs. per regeneration to achieve an economical 24,000 grain capacity (hardness in grains divided into grains of capacity results in the gallons of water that can be treated before resins is exhausted).

2. The national average is 60 lbs. per month, but that can vary depending upon the quantity and the quality of water being treated.
