American Fork hard water · Water softeners · Well water
American Fork tells you what to set your softener to: 12.38 grains.
That number is from the city’s own water FAQ. It’s a softener setting, not a measured hardness, and American Fork’s 2025 water quality report doesn’t list hardness. Most of the city’s water comes from deep wells, which is why it’s hard enough to need one.
American Fork
Deep-well water, and a city that tells you the setting.
American Fork’s water FAQ says most of the city’s culinary water comes from six deep wells, plus a small amount from a spring up American Fork Canyon. Well water picks up calcium and magnesium on the way up, and the city’s answer to “how hard is the water?” is a direct one: set your softener at 12.38 grains per gallon. That’s a setting recommendation, not a published lab result, and the city’s 2025 water quality report doesn’t list hardness at all. Use 12.38 as the starting point, and confirm with a test at your tap before you buy or resize anything.
Already have a softener? A unit set too low leaves spots; set too high it wastes salt. The city’s 12.38 setting is the number to check against.
Why Utah County water is this hard
Where we have a city report, we cite it. Where we don’t, we say so.
Provo runs 10–15 grains (2025 CCR). Orem swings 7–25 (2026 CCR). Lehi’s 2025 city water report doesn’t list hardness, so we don’t have a city number. Vendors cite around 11 grains (2024, not a city figure) — we test your tap before sizing anything. Saratoga Springs publishes a culinary-water average of 142 ppm / 8.3 gpg as CaCO₃ — moderately hard, milder than Provo or Orem. That’s the city’s own number; its 2025 water quality report doesn’t list hardness.

What we actually do
Softener and scale are the front door.
General plumbing rides behind that. We are not trying to be every plumber listing in American Fork. We are the hard-water page.
Water softener
Put it on before scale becomes a repair — especially in a new build.
