Is Brigham City hard water?
At 17-20 grains per gallon, Brigham City 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.
What Brigham City’s hardness means in practice
Sizing is arithmetic once you have a number. At 20.0 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 6,000 grains of hardness through its plumbing every day. Over a year that is about 313 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 5.3 days and a 48,000-grain unit about every 8.0 days. Those are first estimates off the figure Brigham City 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.
What CASA recommends in Brigham City
Brigham City’s figure is high enough that scale is a maintenance cost rather than a nuisance, so a properly sized softener comes first. Reverse osmosis and whole-home carbon handle taste and chlorine separately.
