Is Sandy hard water?
At 181 mg/L, about 10.6 grains per gallon, Sandy 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: This is Sandy's most recent published figure; later reports dropped hardness. Wells typically run only in summer.
Scale builds inside the heater before it is visible anywhere else.
What Sandy’s hardness means in practice
Sizing is arithmetic once you have a number. At 10.6 grains per gallon — the published figure — a household using the EPA average of more than 300 gallons a day sends roughly 3,180 grains of hardness through its plumbing every day. Over a year that is about 166 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 10.1 days and a 48,000-grain unit about every 15.1 days. Those are first estimates off the figure Sandy 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.
