About two-thirds of Erwin's homes predate 1980, and nearly a quarter were built in 1939 or earlier, so many showers here have older valves that need rebuilding or replacing. Call the number on this page to be connected with a local plumber in Erwin.
Erwin's homes and water
Erwin grew as a cotton-mill town next to Dunn on the Cape Fear River. Per Census survey data, its median home was built in 1966, about 66.7% predate 1980 and about 24% date to 1939 or earlier. Showers in homes that age often have compression valves with separate hot and cold handles, sometimes with old supply pipe behind them, and usually without pressure balancing.
Erwin has no town water department; Harnett County bought the water and sewer systems in 2006, so Harnett Regional Water serves the town. Its 2024 water quality report lists chloramines as the main disinfectant (running annual average 2.64 ppm) and a pH of 7.9. Chloramine tends to wear rubber washers and O-rings over time. Hardness isn't reported.
In Erwin's oldest houses, the bathroom may have been remodeled once or twice, so the valve can be newer than the house, or a mix of old and new parts. A plumber will identify what's actually in the wall before recommending a rebuild or replacement, and will check the pipe connections if the valve body has to come out.
What to do now
- Close the main if the shower won't shut off.
- Go easy on old handles. Decades-old stems can strip or snap if forced.
- Check below and behind the shower. Stains or soft plaster suggest a leak at the valve.
- Note the setup. Count the handles and look for a brand name.
- Call to be connected. Mention the home's age so the plumber brings parts for an older valve.
Symptom guide
| Symptom | Likely cause |
|---|---|
| Drip that won't quit | Hardened washer or worn seat |
| Hot spike on a flush | No pressure balancing in the valve |
| Handle won't shut off firmly | Stripped or worn stem |
| Crust around the stems | Mineral buildup or corrosion |
| Stained ceiling below | Leak at the valve body or connections |
What affects the cost
- Rebuilding the valve versus installing a new one
- Finding parts for a very old valve
- Replacing old pipe at the valve
- Opening and patching plaster or old tile
- Converting to a single-handle valve with new trim
Plumbing inspections in Erwin are done by Harnett County, but the town requires its own zoning permit first; the plumber can confirm whether a valve replacement needs a permit.
