To determine the right size water softener for your needs, you should consider the following factors:
-
Number of people in your household: The more people in your household, the larger the water softener you will need.
-
Water hardness: You need to know the hardness of your water to determine the right size water softener. Water hardness is measured in grains per gallon (GPG) .
-
Water usage: The amount of water you use in your household will also affect the size of the water softener you need. A water softener that is too small will not be able to keep up with your needs and will wear down faster, while an over-sized softener means wasted money.
Most water softeners are sized based on the number of people in your household and the hardness of your water. A general rule of thumb is that a 32,000-grain unit (1 cubic foot of resin) is more than enough capacity for the majority of homes. However, there are conditions that would create a need for a larger unit, such as a larger family (6 or more) and/or very hard water (over 15 grains) .
To calculate the proper size of water softener, you can use the following formula:
- Water hardness (in GPG) x Water usage (in gallons) x Number of people in your household / 7,000 = Required grain capacity .
Once you have determined the required grain capacity, you can choose a water softener with a capacity that meets or exceeds that number.
