Hard water is measured in terms of grains of the mineral per gallon or GPG. Sometimes it’s measured in parts per million. If the homeowner wants to know how hard water their water is they should have it tested. If it comes back in PPM they can divide the number by 17.1 to get the GPG. A GPG that’s higher than 7 means that the water is hard. If the GPG is above 10.5, the water is considered very hard and a whole house system to soften the water is recommended. The unit can be connected to the water main and now and again needs to be recharged with salt.
