Permits and water work differently in Middletown
Across most of Butler County, plumbing permits come from the Butler County General Health District. Middletown is one of two exceptions, along with Hamilton, so permitted plumbing work inside the city goes through Middletown's own building department.
Water comes from the City of Middletown's utility, which draws from 13 production wells and treats the water at its own plant before it reaches homes. The city's annual water quality report lists current results, including hardness, and it is worth reading before you buy a softener.

Sewer backup or burst pipe in Middletown? Steps before we arrive
Stop the water
Close the main shutoff, usually on the basement wall facing the street in older Middletown homes. If it will not turn, do not force it.
Stop using drains
If sewage is coming up a floor drain, stop running water, flushing and laundry until the line is cleared.
Stay safe around power
Keep out of standing water near outlets or appliances and switch circuits off from a dry spot.

Older homes near downtown, newer ones toward I-75
Middletown grew up around its steel mill and the paper industry, and many homes near downtown Central Avenue and the Sorg Opera House date from the first half of the 1900s. Those houses share the same plumbing problems as Hamilton's older neighborhoods: cast iron drains, clay sewer laterals with root intrusion, and galvanized supply lines that narrow with rust.
Newer subdivisions on the east side toward I-75 and the Warren County line have copper or PEX supply and plastic drains, where the calls are more about water heaters and sump pumps. Older homes are where sewer line repair and repiping come up most.
Plumbing emergency in Middletown? We answer 24/7.
Call (513) 796-9381When to call the city and when to call a plumber
- Water main break or no water on the whole street: Middletown's water department.
- Sewage backing up in only your house: a plumber, since the lateral is usually the cause.
- Leaking water heater or burst pipe: close the shutoff and call our 24/7 line.
- Smell of gas anywhere: leave, then call the gas utility or 911 from outside.
Clearing a backed-up main line usually starts with drain cleaning and a camera look at the lateral.
