Frequently Asked Questions About Water Heater Repair in Dardenne Prairie, MO

First, find the cold water valve above the heater and turn it clockwise to stop the water flow. Second, turn off the power (flip the breaker for electric, or turn the gas valve to 'off' for gas). Finally, call Water Heater Repair Tech at (877) 415-0636 for emergency service in Dardenne Prairie, MO.
A gas burner should have a crisp blue flame. A yellow or orange flame indicates that the burner is not getting enough oxygen for complete combustion, which can produce dangerous carbon monoxide. It needs immediate cleaning and adjustment.
A pilot light that repeatedly goes out is usually due to a bad thermocouple. The thermocouple is a safety device that senses the flame; if it fails, it shuts off the gas. Call (877) 415-0636 and we can replace it quickly.
A puddle could mean a leaking drain valve, a leaking pressure relief valve, condensation, or a rusted-through tank. Dry the area and see where the drip is originating. If it's coming from the bottom of the tank itself, you need a replacement.
If your home is on a closed plumbing system (such as having a pressure reducing valve), thermal expansion can cause dangerous pressure spikes when water heats up. An expansion tank absorbs this pressure and protects your water heater.
