Water heater repair fixes problems like no hot water, lukewarm water, leaks from fittings, or popping and rumbling noises. Call 540-200-2302 to get connected with a licensed local plumber who repairs gas, electric and tankless water heaters in the Roanoke area.
Troubleshooting no hot water
- Electric heater: check the breaker. A tripped breaker or failed heating element is a common cause.
- Gas heater: check whether the pilot light is out. If you smell gas, leave and call 911 or your gas utility from outside.
- Lukewarm water only: often sediment buildup or a failing element or thermostat.
- Water around the base: a leaking tank usually means replacement. Shut off the cold-water supply valve on top and the power or gas.
Common water heater repairs
- Heating element or thermostat (electric): the usual fix for no hot water or lukewarm water.
- Thermocouple, igniter or gas valve (gas): the usual fix when the pilot won't stay lit.
- Relief valve dripping or leaking: replaced as a safety part.
- Leaking fittings or supply lines at the top of the tank: usually repairable.
- Sediment causing rumbling or short hot-water supply: a flush often helps.
- Tankless error codes and scale buildup: descaling and part replacement. See tankless water heaters.
Repair or replace?
If water is leaking from the tank itself, or the unit is past its typical 8 to 12 year life, replacement is usually the better value. A failed part on a younger heater is usually worth repairing.
See what a new one costs on our water heater replacement and installation page.
How to make a water heater last longer
- Have the tank flushed to remove sediment. Many manufacturers suggest yearly.
- Have the anode rod checked every few years.
- Test the temperature-and-pressure relief valve.

Common questions
Should I repair or replace my water heater?
If the tank is leaking or the unit is near the end of its typical 8 to 12 year life, replacement is usually the better choice. A failed element or thermostat on a younger unit is often worth repairing.
Is a leaking water heater an emergency?
It can be. Shut off the cold-water supply valve and the power or gas, then call. See our emergency plumber page.
Do I need a permit to replace a water heater?
Often, yes. Ask the contractor whether the permit and inspection are included in the quote.
