Common questions about water heater repair in Rochester.
A water heater producing no hot water in Rochester can be caused by a tripped circuit breaker for electric units, a failed pilot light or gas valve for gas units, a burned-out heating element, a failed thermostat, or a tripped high-temperature limit switch. Magnet Plumbing diagnoses the specific cause and repairs it on the same visit whenever possible.
Yes. Magnet Plumbing services all major tankless water heater brands in Rochester, NH — diagnosing and repairing error codes, flow sensor failures, heat exchanger scale buildup, gas valve malfunctions, and igniter problems. Tankless units can often be repaired rather than replaced, and our plumbers carry common repair components for same-visit repairs when available.
Tank water heaters in Rochester typically last 8 to 12 years with normal use and basic maintenance. Hard water accelerates sediment buildup and reduces lifespan. Annual anode rod inspection and occasional flushing extends tank life. Tankless water heaters generally last 15 to 20 years with proper maintenance and periodic descaling.
Water heater repair in Rochester typically costs $150 to $500 depending on the component being replaced. Common repairs like thermostat replacement, heating element swap, or T&P valve replacement are on the lower end. Gas valve or burner assembly replacement costs more. Magnet Plumbing provides a free diagnostic and written estimate before performing any repairs.

"My hot water was not working so they replaced and adjusted the regulator valve, then repaired the shower diverter and replaced the hot and cold valves. Now I can easily have hot water and it feels like a new shower again. They even picked up the parts I had ordered in Hollywood at Ferguson Plumbing Supply."
"Main water line burst and we had a river in the front yard. They isolated the break, got the water back on within a few hours, and replaced the section cleanly the next day. Excellent emergency response."
"I called many places to see if someone could come and install a much needed commercial sink at work. Saul called me back and said he could be there in a few hours, and 3 hours later he showed up and installed the sink, faucet and replaced a broken toilet we had."
