Most water heater breakdowns, from no hot water to a short supply or a leaking relief valve, trace back to one part such as an element, thermostat, thermocouple or valve. A tank that leaks from its shell can't be fixed and has to be replaced. Call the number on this page to be connected with a local plumber in Winston-Salem who can find the cause.
Start with the symptom
| Symptom | Likely cause |
|---|---|
| Electric heater, no hot water at all | Tripped breaker, tripped high-limit switch, failed element or thermostat |
| Gas heater, no hot water | Pilot gone out, worn thermocouple or flame sensor, faulty gas control |
| Hot water runs short | Upper or lower element out, cracked dip tube, sediment taking up space |
| Rumbling or crackling sounds | Sediment layer at the bottom of the tank |
| Discharge from the relief valve line | Excess temperature or pressure, or a tired valve |
| Puddle at the base | Leaky drain valve or connection, or a tank that has failed |
What you can safely check
For an electric unit, look for a tripped breaker. For a gas unit, see whether the pilot is out and relight it only by following the instructions printed on the heater. Stop there. Electric models run on 240 volts, and gas valves and flue venting belong to a professional. A relief valve that is releasing water is doing its job, so never plug or cap it.
How Winston-Salem's water affects the tank
Winston-Salem/Forsyth County Utilities reports soft water, with hardness averaging about 17.5 ppm in its 2025 water quality report. That means less scale than many areas see, though grit and sediment still collect in a tank, so draining a few gallons from the bottom now and then is worthwhile. The utility disinfects with chlorine, and a faint chlorine smell at the tap is from the water supply, not a heater problem.
When repair stops making sense
The Department of Energy puts a storage water heater's expected life at about 10 to 15 years. A failed element or thermocouple on a five-year-old heater is an easy repair. A unit near or past that age that needs an expensive control, or one showing rust or weeping from the tank, is usually better replaced. The date of manufacture is coded on the rating label, and a plumber can read it for you.
Factors in the price
Cost depends on the part, gas or electric, where the heater sits (attics and tight crawl spaces add labor), and whether the visit falls after hours. Ask how the diagnostic visit is charged and get a quote for the repair before work starts.
