Is South Salt Lake hard water?
At 43.9-191 mg/L, South Salt Lake sits in the very hard band — above about 10.5 grains per gallon is very hard on the USGS scale. Scale shows up first inside the water heater, then on fixtures and glass. See the hardness scale.
Worth knowing: Must be published with the year visible; 2023-2025 reports dropped hardness, and the city has several water providers so one number is approximate.
Scale builds inside the heater before it is visible anywhere else.
What South Salt Lake’s hardness means in practice
Sizing is arithmetic once you have a number. At 11.2 grains per gallon — the top of that range, because a softener sized for the soft months lets hardness through in the hard ones — a household using the EPA average of more than 300 gallons a day sends roughly 3,351 grains of hardness through its plumbing every day. Over a year that is about 175 pounds of scale-forming calcium and magnesium passing through the water heater and the fixtures.
Against that load a 32,000-grain softener would regenerate roughly every 9.5 days and a 48,000-grain unit about every 14.3 days. Those are first estimates off the figure South Salt Lake publishes, not a quote: your own use, any iron in the water, and whether you want softened water at the kitchen tap all move the answer, which is why we measure at your tap before sizing anything.
