What size softener does a Fremont home need?
Once you know your hardness, our calculator gives you the right softener size and price range in seconds.
Is a softener worth it here?
Hard water costs you in slow ways: scale shortens the life of water heaters, dishwashers and washing machines, clogs showerheads, and makes soap less effective. On the University of Nebraska scale, anything over 7 grains per gallon is "hard" and over 10.5 is "very hard." Most households in that range notice a difference with a softener.
