A Lexington plumbing inspection is a plumber's check of the supply and drain piping, water heater, valves, fixtures and, if you want it, the sewer lateral by camera. About two-thirds of the city's homes were built before 1980, so the visit often comes down to finding out how much original pipe is left.

Lexington's plumbing picture
Lexington has one of the older housing stocks in the area. Census survey data puts the median home at 1969, with about 68% built before 1980 and roughly 14% before 1940. The Uptown, Lexington Residential and Erlanger Mill Village historic districts hold many of the oldest houses, where galvanized supply lines, cast-iron drains and decades of mixed repairs are common.
The City runs its own water, sewer and natural gas systems. Water comes from Lake Thom-A-Lex and is treated with chlorine, and the 2025 report shows no violations. The City has posted a full service line inventory online and at City Centre on North State Street, so a buyer can look up how a given address is listed before the plumber arrives. The report says the City is responsible for removing lead pipes, while residents share responsibility for plumbing at the home.
City policy requires backflow protection on every irrigation system, residential ones included, with a yearly test by a City-approved tester at the owner's cost. A pool added later can also prompt the City to require a device.
Plumbing inspection versus general home inspection
| Item | General home inspection | Plumber's inspection |
|---|---|---|
| Supply pipe | Notes visible material | Identifies pipe type, tests pressure, looks for hidden corrosion |
| Drains | Runs fixtures briefly | Checks slope, venting and the main drain, with an optional camera run |
| Water heater | Notes age and venting | Checks the relief valve, expansion control, burner or elements |
| Gas piping | Visual only | Can look over fittings, shutoffs and connections at appliances |
| Irrigation backflow | Often skipped | Confirms a device is present and whether a test record exists |
Signs it's time
- Rust-tinted water from one fixture but not others
- Slow drains that come back soon after clearing
- Low pressure that has crept down over the years
- Gas appliances that are old or were moved without clear records
Timing notes
Book early in a due diligence window so there is time for quotes on anything found. Repairs that need permits go through the City's permitting office and its online portal. If you smell gas at any point, leave the house and call 911 or the City of Lexington's gas utility from outside, not a plumber.
