Worth knowing: Pleasant Grove publishes three zones split at 500 East and 1800 North, and hardness nearly doubles across the city.

What Pleasant Grove’s hardness means in practice
Sizing is arithmetic once you have a number. At 28.7 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 8,610 grains of hardness through its plumbing every day. Over a year that is about 449 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 3.7 days and a 48,000-grain unit about every 5.6 days. Those are first estimates off the figure Pleasant Grove 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.
