Is Riverdale hard water?
At 12 gpg, Riverdale 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: Undated standing FAQ; 2025 CCR has no hardness row.
Scale builds inside the heater before it is visible anywhere else.
What Riverdale’s hardness means in practice
Sizing is arithmetic once you have a number. At 12.0 grains per gallon — the published figure — a household using the EPA average of more than 300 gallons a day sends roughly 3,600 grains of hardness through its plumbing every day. Over a year that is about 188 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 8.9 days and a 48,000-grain unit about every 13.3 days. Those are first estimates off the figure Riverdale 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 Riverdale
At the hardness Riverdale publishes, a correctly sized softener earns its keep in water heater and fixture life. Reverse osmosis at the kitchen sink handles taste; whole-home carbon takes chlorine out at every tap.
