When an Erwin water heater leaks from the tank, gives rusty water or keeps failing, replacement is usually the right move. Erwin's homes are among the oldest in the area, so the job often includes updating parts around the heater. Call the number on this page to be connected with a local plumber in Erwin.
Erwin is a former cotton-mill town next to Dunn on the Cape Fear River. About 24% of homes were built in 1939 or earlier and roughly two-thirds before 1980, with a median of 1966, per Census survey figures. In houses that old, heaters were often added decades after construction and set wherever there was room: a closet, back porch or kitchen corner, with old valves and relief lines. A replacement is a good time to move one onto a pan or out of living space, though relocating adds plumbing and permit work.
Erwin has no town water department. Harnett County bought the water and sewer systems in 2006, so service and billing go to Harnett Regional Water, which uses chloramine as its main disinfectant (a 2.64 ppm average in 2024).
What to do right away
- Close the cold-water valve above the heater to stop a leak.
- Turn off power or gas. Flip the breaker or set the gas control to off.
- Gas smell? Leave and call 911 or Piedmont Natural Gas at 800-752-7504 from outside.
- Protect old floors. Mop up and note any soft or stained flooring near the heater.
- Collect the basics. Fuel, gallons, age and location. Mention whether the heater is in a closet, on a porch or in another tight spot, since that affects which tank fits through the door.
- Call. A local plumber can confirm the replacement and handle the zoning and county permit steps.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Puddle under the heater | Corroded tank or failed valve |
| Rusty hot water | Tank corrosion or spent anode |
| Relief valve leaking | High pressure or temperature, or a worn valve |
| Little hot water | Sediment, element or burner problem |
| Soot near a gas burner | Poor draft or combustion; call a plumber |
Plumbing inspections in Erwin are done by Harnett County Inspections, but the Town requires its own zoning permit first. The plumber can take care of both, and an inspection gives the venting and relief line on an older-home install a second look.
Cost factors
- Size, fuel and efficiency
- Older-home work: valves, connectors, relief line, venting
- Relocating a heater from an unsuitable spot
- Drain pan or expansion tank
- Zoning and county permit, plus disposal
