The softener capacity is calculated in three simple steps:
- 1. Convert water hardness from ppm to grains per US gallon Total Hardness (ppm) = Total Hardness (gpg) Example: 118 ppm TH = 6.9 gpg; 17.1 17.1
- 2. Calculate softener capacity in grains Ft3 resin X resin exchange capacity (typically 30,000 grains/ft3) = Grains capacity Example: 6 ft3 resin X 30,000 grains/ft3 = 180,000 grains of capacity
- 3. Calculate softener capacity in gallons
- Multiply the number of people in your family times 70 (gallons of water used per day, national average).
- Multiply the answer by your water hardness in grains per gallon (to convert mg/l or ppm to grains, divide by 17.1). ...
- This is your "grains per day" number.
