Is Orem hard water?
At 7 to 25 grains per gallon from city sources, 6.6 to 9 from the regional plant, Orem 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: About 60 per cent of Orem's supply is surface water from the regional plant and 40 per cent city wells and springs, so where your tap lands in that spread moves with the season.
It costs in water heater life and in detergent long before it is visible.
What Orem’s hardness means in practice
Sizing is arithmetic once you have a number. At 25.0 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 7,500 grains of hardness through its plumbing every day. Over a year that is about 391 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 4.3 days and a 48,000-grain unit about every 6.4 days. Those are first estimates off the figure Orem 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 Orem
At the hardness Orem 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.
