What shapes water heater trouble in Johnstown
Deep wells, a 1995 plant
Johnstown's water comes from three groundwater wells on the grounds of Belt Park, next to the treatment plant at 395 West Jersey Street. The plant, finished in 1995, handles about a million gallons a day, and the city's water tower came online in 2002. The aquifer sits more than 130 feet down under thick clay, and Ohio EPA rated its risk of contamination as low.
Operators test hardness every day, but the city's 2025 report doesn't publish a hardness figure. If your heater rumbles or you're weighing a softener, ask the water plant at (740) 967-1139 what it measures.
No lead listed, some galvanized pipe
The city's posted service line inventory lists about 2,200 lines and none marked lead. About 80 customer-side lines are galvanized steel, and a few hundred are still marked unknown. Galvanized pipe rusts from the inside as it ages. If only your hot water runs brown, the tank is the likely source; if the cold runs brown too, the pipe may be.
In 2024 testing, no lead sample was over the action level. For a lead test at home, the city points residents to the Licking County Health Department at 740-349-6535.
Renters: Ohio law covers hot water
About 38% of Johnstown households rent, and about 16% of homes are in buildings with five or more units. Ohio law requires landlords to supply reasonable amounts of hot water and to keep the plumbing and appliances they provide in working order. If you rent, tell your landlord in writing, and if the tank is leaking, shut off the cold supply valve above it.
County permits, curbside bulk
Plumbing permits in Licking County come from the Licking County Health Department, which lists a water heater as a fixture on its residential application. About 75% of Johnstown homes heat with gas and 22% with electricity, and the city lists AEP and The Energy Co-op for electric service.
Local Waste Services has collected Johnstown's trash since 2016. Bulk items go out with regular pickup, and the hauler asks you to call its office first. Freon appliances cost $50 each.
