How do I know how hard my water is?

Check with municipal water authorities to determine your water hardness. If a water softener is installed, check to be sure it is working properly. We recommend consumers have their water softener hardness level set at 3-4 gpg vs. totally softened water (0-1). Hard water areas use more detergent and soft areas use less. Refer to the “Adding Detergent” section for recommended detergent amounts.
