Answers to frequently asked water heater repair questions from Sandown homeowners.
A water heater producing no hot water in Sandown 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.
If your water heater in Sandown is under 8 years old and the repair cost is less than 50% of the replacement cost, repair is generally worthwhile. If the unit is over 10 years old, has rusted or corroded components, or has a tank showing signs of failure, replacement is the more economical long-term choice. Magnet Plumbing gives you an honest assessment.
Water heater leaks in Sandown homes can come from the pressure relief valve releasing due to over-pressure or temperature, loose inlet or outlet connections, a corroded drain valve, or — most seriously — a crack in the tank itself. Tank leaks typically mean the unit needs replacement. Magnet Plumbing inspects the source of the leak and advises on repair vs. replacement.
Rusty or discolored hot water in a Sandown 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.
Our reputation is built on results. Here is what our customers have to say.
"Once again Magnet Plumbing came to save the day. I manage a building of 49 units and we had a gas leak somewhere. The city shut the gas for the whole building. They showed up right away and got to work. They found the problem, fixed it, and were able to turn the gas back on so people could have dinner. Saul is amazing — right on time, very professional."
"Our main line backed up on a Saturday night and the Magnet Plumbing crew showed up within the hour. They cleared it, camera inspected it, and gave us a quote to fix the damaged section. Professional from start to finish."
"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."
