Frequency of Regen
To determine the frequency of regeneration, you will first find the estimated capacity of the softener and divide that by the appropriate number of gallons used per day.
How to Measure you Water Hardness
Use the hardness test strips to test the hardness of the water source.
Estimated Capacity of your Water Softener
The number of gallons a softener will use depends on the hardness of the water source and your water usage. To determine the approximate capacity of your unit, take the grains of the unit (Standard 8,000/Double 16,000) and divide the grains per gallon (GPG) of the water source.
Calculating Frequency of Regeneration
Divide the grains of the softener by the GPG of the water source (the red numbers on our test strip bottles, goes up to 58 GPG)
- Standard Softener
- 8,000 / 11 GPG = 727 gallons used per day
- 8,000 / 58 GPG = 137 gallons used per day
- Double Standard Softener
- 16,000 / 11 GPG = 1,454 gallons used per day
- 16,000 / 58 GPG = 275 gallons used per day
Divide the estimated capacity by the number of gallons you use per day. We figure that the average couple uses 50 gallons per day.
- Standard Softener
- 727 gallons / 50 = 14 days
- 137 gallons / 50 = 2.5 days
- Double Standard Softener
- 1,454 gallons / 50 = 29 days
- 275 gallons / 50 = 5.5 days
If you go too long before performing the regeneration process, a few things may happen: your unit may not last very long, or after the regeneration process, the strips will not test between 0-3 GPG at the output of the softener. This can easily be corrected by performing a special regeneration process. For the special regeneration process, you double the salt and double the slow rinse time.
