Lexington has one of the oldest housing stocks in the area, so a dripping or unstable shower here is often an older compression or early single-handle valve wearing out. Some can be rebuilt with new stems and seats; others are better replaced. Call the number on this page to be connected with a local plumber in Lexington.
Why Lexington shower valves wear the way they do
About two-thirds of Lexington homes were built before 1980, with a median build year of 1969, and about 14% predate 1940, per Census survey data. That covers the Erlanger Mill Village and the city's residential historic districts, where bathrooms may still have two- or three-handle valves with rubber washers and brass seats. Those valves were built to be serviced, and many can be rebuilt. The harder cases are early single-handle valves whose cartridges are no longer made, and old galvanized supply piping feeding the valve.
The City of Lexington supplies water from Lake Thom-A-Lex and disinfects with chlorine, reporting a running annual average of 0.79 ppm and no violations in its 2025 report. Chlorine at that level is not unusual, but over decades it still dries out washers and O-rings. The report does not list hardness, so a plumber checks for scale on the parts rather than assuming either way.
Rebuild or replace: how the options compare
| Option | What it involves | When it fits |
|---|---|---|
| Washer and seat rebuild | New washers, seats and packing on a two- or three-handle valve | The valve body is sound and stems are still available |
| Cartridge swap | Pulling the old cartridge and fitting a matching new one | A single-handle valve from a brand that still makes parts |
| New valve body | Opening the wall or an access panel and replacing the valve and trim | Cracked body, leaking joints, or no parts left for the model |
Signs to look for
- A drip from the showerhead that never quite stops
- A hot handle that has to be cranked harder each month to shut off
- Water that runs hot one minute and cool the next
- Rust-colored water at the shower only, which can point to old piping feeding the valve
- Soft drywall or loose tile near the trim
Timing and the seasons
Cold-weather months bring colder water off the lake, so the shower needs more hot water to feel the same. A worn valve or a limit stop set during summer can leave winter showers lukewarm. If a valve needs replacing, doing it before winter avoids that stretch. Permits for plumbing work go through the City of Lexington's permitting office and its online portal, and the plumber can tell you whether a valve replacement needs one. If your water heater runs on natural gas in town, that service comes from the City's own gas system rather than Piedmont Natural Gas.
