Frequently Asked Questions About Water Heater Repair in Barnhart, MO

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.
This unpleasant odor happens when bacteria in your water react with the magnesium anode rod inside the tank. We can resolve this in Barnhart, MO by flushing the tank and replacing the standard rod with an aluminum-zinc or powered anode rod.
Low hot water pressure is usually caused by scale buildup inside the water heater's pipes, or a faulty shut-off valve. If cold water pressure is fine, the issue is isolated to the hot water system and our technicians can clear the blockage.
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 Barnhart, MO.
Yes, we do. Water Heater Repair Tech is available around the clock for emergency water heater situations throughout Barnhart, MO. You can count on us nights, weekends, and holidays when major leaks or complete heating failures happen.
