What shapes water heater trouble in South Lebanon
Cincinnati water, two different billers
South Lebanon's 2025 water report says the city receives all of its drinking water from Greater Cincinnati Water Works, which draws from the Ohio River and the Great Miami Buried Valley Aquifer. GCWW's Miller plant averages about 7 grains per gallon of hardness and its Bolton plant about 8, so tanks here collect some scale and sediment over the years.
In the city's 2025 lead testing, the 90th percentile result was 5.5 ppb and none of 20 homes was over the 15 ppb action level. Homes in Auburn Grove, Stonebrook, Vista Pointe, River's Edge, Wynstead and the Villages of Rivers Bend get water from Warren County Water and Sewer at (513) 695-1377 instead, with city sewer and trash on the same county bill.
A young housing stock
Census estimates put the median South Lebanon home at 2007, with about 66% built in 2000 or later. About 73% are detached houses and about 27% of households rent. Gas heats about 55% of homes and electricity about 40%. When an electric tank runs out of hot water fast, a failed element or thermostat is a common cause, and both can usually be replaced without a new tank.
County plumbing permits
Plumbing work in Warren County is reviewed and inspected by the Warren County Health District. Its fee list includes a water heater only permit for $50, and fees double if work starts before the application is filed. The city itself runs water, sewer and trash service from 10 North High Street, (513) 494-2296.
Safe steps for South Lebanon 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 Duke Energy at 800.634.4300 from outside. Duke's Ohio gas tariff lists South Lebanon among the communities it serves.
