Frequently Asked Questions About Water Heater Repair in Dover, NH
Yes. We provide full tankless water heater maintenance, descaling flushes, and error code diagnostics. If your tankless unit has scale buildup or an ignition fault, our certified technicians in Dover, NH can service it on the same day.
Low hot water pressure is typically caused by heavy mineral scale clogging the water heater's hot outlet nipple, a partially closed shut-off valve, or a defective heat trap. Our technicians can clean or replace the fittings to restore full flow.
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.
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.
In electric water heaters, lukewarm water usually means the upper element is functioning but the lower element has burned out. In gas units, it often indicates a damaged dip tube or a miscalibrated thermostat control.
