How to Size Your Water Softener?
This is the formula to properly Size Your Water Softener
# of people in the House X # Gallons Water Consumption Per Person X Grains Per Gallon = Is Equal to the Number of Grains to be removed
4 People living in my House x 75 Gallons of water consumer per person (average) X The Grains in my area 10 = 3000 Grains to be removed Daily
Then You have to look at this Chart and Find the right Softener Capacity
What do your results mean?
Note: Calculations are based upon your softener regenerating on an average of every seven days.
If Your Daily Grain Requirements Are: You Need a Water Softener With:
0 - 3,500 Grains Per Day ---- 24,000 Grain Capacity
3,501 - 4,500 Grains Per Day ---- 32,000 Grain Capacity
4,501 - 5,750 Grains Per Day ---- 40,000 Grain Capacity
5,751 - 6,850 Grains Per Day ---- 48,000 Grain Capacity
6,851 - 9,150 Grains Per Day ---- 64,000 Grain Capacity
9,151 - 11,500 Grains Per Day ---- 80,000 Grain Capacity
11,501 - 13,700 Grains Per Day ---- 96,000 Grain Capacity
13,701 - 15,700 Grains Per Day ---- 110,000 Grain Capacity
Therefore I need a 24,000 Grain Capacity Water Softener
