When choosing a softener tank size, it is important to know a couple of things:
- Hardness of existing water (in PPM or Grains)
2. Approximate demand flow (gallons per minute)With these two components, you can determine approximate daily flow of your softener system and the amount of capacity necessary in a softener tank to last at least 24 hours.Below, fill in the approximate hardness value and demand flow for your desired system.With the KiloGrains of hardness / 24 hrs, you can compare to capacity of different size tanks. Choose a Tank size that has minimally the calculated KiloGrain value in the calculator.
