Water Heater Repair in Troy, OH
Troy pumps its water from 10 wells beside the Great Miami River, and about 16% of its homes were built before 1940. If your water heater has quit or is leaking, call and get a plumber out.
What shapes water heater trouble in Troy
Aquifer wells and a mineral coating
Troy draws its water from sand and gravel aquifers tied to the Great Miami River, using 10 production wells at Miami Shores Golf Course and Community Park. The plant on East Staunton Road pumped an average of about 3.66 million gallons a day in 2025, and the city logged 36 water main breaks that year.
The 2025 report lists average hardness at 117 ppm, about 7 grains per gallon. The city says it tunes its water chemistry to lay down a very thin calcium carbonate coating inside pipes and fixtures as protection against lead. Heating water makes calcium carbonate settle faster, so a tank still slowly gathers scale, and flushing it now and then helps.
The plant, first built in 1971, has used chlorine gas to disinfect. In September 2025 the city announced a $2.2 million switch to liquid sodium hypochlorite, set to finish by the end of 2026, and said residents shouldn't notice a change in their water.
Homes built before 1944
Troy banned lead service lines in 1944 and says it has replaced all known lead and galvanized lines on the public side. It estimates about 2,000 private-side lines still need to be identified, and only homes built before February 1, 1944 could have lead. Owners of those homes get a yearly letter until the line is checked or replaced.
A city technician can check the pipe where it enters your home in about 15 minutes, weekdays 8 a.m. to 3 p.m. Call 937-335-4151 or email [email protected]. In 2025 lead testing, none of 30 samples was over the action level.
Mixed ages, mostly gas
The median Troy home was built in 1972. About 16% date from before 1940 and about 22% from 2000 or later, and about 72% are detached houses. About 34% of households rent. If you rent, tell your landlord first, and shut the cold supply valve above the heater if it's leaking. About 74% of homes heat with gas and 25% with electricity.
County permits, special trash pickup
Miami County Building Regulations handles residential permits inside Troy. Its permit list covers installing, altering or repairing water supply or gas supply systems and heat-producing appliances, while general maintenance needs none. The office is at 1506 One Stop Court and answers 937-440-8121.
Troy picks up water heaters as special trash on your normal trash day. Set the old tank at your usual trash spot, apart from the bags. The city won't take anything containing Freon, so a heat pump water heater needs another route. Questions go to Central Maintenance at 937-335-1914.
Safe steps for Troy homes
- Leaking? Close the cold water valve on top of the tank.
- Turn off the gas valve or the breaker for the heater.
- Gas smell? Leave the house, then call 911 and your gas utility from outside. National Fuel, which now runs the former CenterPoint Energy Ohio gas utility, answers 1-800-838-0933 around the clock.
