Answers to frequently asked water heater repair questions from Cohasset homeowners.
A water heater producing no hot water in Cohasset 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.
Rusty or discolored hot water in a Cohasset home usually indicates an anode rod that has been depleted and the tank is beginning to corrode internally. In some cases it is sediment stirring from the tank bottom. If the unit is over 8 to 10 years old and producing rust-colored water, tank replacement is often the recommended solution.
Water heater repair in Cohasset 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.
Rumbling, popping, or banging sounds from a water heater in Cohasset usually indicate sediment buildup on the bottom of the tank. Mineral deposits from hard water accumulate over time and overheat, creating the noise. Flushing the sediment can restore quiet operation. If the tank is old and heavily scaled, replacement may be more cost-effective than repeated flushing.
Our reputation is built on results. Here is what our customers have to say.
"Saul and crew are the best. Replaced our water heater, re-piped, and gassed up our kitchen and laundry room. Honest, fair, efficient, and went above and beyond. I could not have asked for a better experience. Highly recommend. Thank you!"
"Smelled gas in the basement late at night and called the emergency line. A plumber was dispatched within the hour, located the leak at a corroded fitting on the water heater gas line, and repaired it on the spot. They even came back the next day to re-verify with the gas detector. Truly appreciated the care taken."
"Fast response, fair price, and they cleared a stubborn bathroom sink clog I had been fighting for a week. Will definitely call again."
