Frequently Asked Questions About Water Heater Repair in Fairfax, VA

A pilot light that won't stay lit is usually caused by a faulty or carbon-coated thermocouple, a blocked pilot orifice, a defective gas valve magnet, or poor combustion air intake. Call (877) 276-9926 to have a technician test and replace the thermocouple safely.
You can improve efficiency by insulating hot water pipes, installing an external fiberglass tank blanket (on electric models), flushing sediment, and setting the thermostat to a safe, efficient 120°F (49°C).
When water heats up, it expands by about 2% to 3%. In homes with a backflow preventer or check valve, this expansion creates severe pressure spikes. A thermal expansion tank absorbs this pressure, preventing leaks and protecting your warranty.
The dedicated water shut-off valve is located on the cold water inlet pipe entering the top of your water heater. It is usually a red or blue ball valve lever or a round gate valve wheel.
A sulfur odor is usually caused by anaerobic bacteria in your water supply reacting with the tank's magnesium sacrificial anode rod. Our technicians in Fairfax, VA can sanitize the tank and install an aluminum-zinc or powered titanium anode rod to neutralize the smell permanently.
