Frequently Asked Questions About Water Heater Repair in Demarest, NJ

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.
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.
Hissing usually happens when condensation from the tank drips down onto the hot burner beneath it. It can also happen if there is a tiny leak spraying onto a hot surface. Have a professional inspect it to be safe.
Absolutely. Our technicians are trained to repair all major brands including A.O. Smith, Rheem, Bradford White, State, Rinnai, and Navien. Whether you have a standard tank or a high-efficiency tankless system, we carry the right parts. Contact (877) 415-0636 for help.
A good rule of thumb is the 10-year mark. If your tank is less than 10 years old and the issue is a faulty part (like a thermostat or element), repair is usually best. If the tank itself is leaking from the bottom due to rust, a full replacement is required.

"I called Water Heater Repair Tech for a second opinion on a repair. Their technician proved that my gas valve was fine and just replaced the $30 thermocouple. My water heater has been working perfectly ever since."
"There was a constant puddle under the pressure relief valve on our water heater. The technician from Water Heater Repair Tech diagnosed high home water pressure, installed an expansion tank, and replaced the valve. Problem completely solved."
"I couldn't find anyone who knew how to work on my Rinnai tankless system until I found Water Heater Repair Tech. The tech quickly found the error code, flushed out the heat exchanger, and the system works perfectly again."
