Results Table

Compare your water test strip to this results table to determine the hardness level of your home’s water. The color of your test strip and the corresponding number indicates how hard your water is. Water hardness levels are measured in grains per gallon (gpg).

If your number is 7 or higher, a water softener is recommended.

If your home’s water tests in the 0-3 grains per gallon (gpg) range, a water softener is not needed as you are already enjoying soft water in your home.
