Water heaters and water softeners in Jerome County, Idaho
In Jerome, Eden and Hazelton, homes rely on groundwater that is hard enough to leave spots on dishes and scale in water heaters. We look after water heater and water softener projects across Jerome County, from in-town homes to farms and shops on private wells.

Hard water in Jerome
Published estimates for Jerome put hardness at about 13 grains per gallon (around 220 to 230 mg/L). That is above the U.S. Geological Survey's very hard level of 10.5 grains per gallon.
City water and private wells
The City of Jerome's water system draws on groundwater and serves about 13,000 people. Many rural homes use private wells instead. Well water quality is not regulated by the State of Idaho, so a hardness test of your own well is the best guide to sizing a softener.
Permits
In Idaho, plumbing work, including installing a water heater, needs a permit. Depending on your address it comes from your city or from the state Division of Occupational and Professional Licenses. We check which applies to your home when we quote.
