Frequently Asked Questions About Water Heater Repair in Union, NH

You can lower your energy bill by turning the thermostat down to 120 degrees, insulating the hot water pipes extending from the unit, and having the tank flushed annually to ensure optimal heat transfer.
Rusty hot water is a strong warning sign that the inside of your tank is beginning to corrode. If the anode rod is completely gone, the steel tank itself rusts. Call us immediately before the tank rusts through and floods.
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 Union, NH.
Yes, we can install a hot water recirculation system. This pump keeps hot water constantly moving through your plumbing lines, so hot water is waiting for you at the tap the moment you turn it on.
No, a leaking Temperature and Pressure (T&P) valve means there is either excessive pressure inside the tank, the temperature is dangerously high, or the valve itself has failed. This is a safety issue that should be addressed immediately.

"Our hot water smelled awful, like rotten eggs. The plumber from Water Heater Repair Tech explained it was a reaction with our anode rod. He flushed the tank and put in a special aluminum-zinc rod. The water smells perfect now."
