What shapes water heater trouble in Parma
Six wells, chlorine only
The City of Parma draws its water from six wells around town, and its 2025 report describes the treatment as disinfection with chlorine. It mentions no softening and doesn't list a hardness figure. It does show arsenic at 4 to 5 ppb, under the federal limit of 10, and lead at 1 ppb at the 90th percentile with no homes over the action level.
Unsoftened well water carries its minerals into your tank, where they settle as sediment over time. Draining a few gallons from the valve once or twice a year keeps it in check. Water questions go to City Hall at 208-722-5138.
Cold nights on the Snake River
NOAA's normals for the Parma Experiment Station, at the University of Idaho's research center in Parma, show about 144 nights a year at or below freezing and an average January low near 23°F. Cold incoming water makes a heater work harder in winter, and a tank in an unheated space loses heat faster.
Mobile homes and 1970s houses
About 20% of Parma homes are mobile or manufactured homes. Federal rules require heat-producing appliances in manufactured homes to be listed for that use, with fuel-burning units vented outside, so a standard store-bought heater may not be the right replacement. The median Parma home was built in 1974, about 34% of households rent, and heating splits almost evenly: about 49% gas and 47% electric.
State plumbing permits, county landfill
In Idaho, plumbing permits are sold by the Division of Occupational and Professional Licenses (DOPL) where a city doesn't run its own program, and DOPL's inspector list assigns state plumbing and electrical inspectors to Parma's ZIP code. A local building permit doesn't replace the DOPL permit. Call DOPL at 208-334-3233.
Canyon County's Pickles Butte landfill, at 15500 Missouri Ave. south of Nampa, is open Monday through Saturday, 8 a.m. to 5:30 p.m. Call the scale house at 208-466-7288 about an old tank before you haul it.
Safe steps for Parma homes
- Leaking? Close the cold water valve on top of the tank.
