Answers to frequently asked water heater repair questions from South Hempstead homeowners.
A water heater producing no hot water in South Hempstead 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 South Hempstead, NY — 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 South Hempstead 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 leaks in South Hempstead 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.
Our reputation is built on results. Here is what our customers have to say.
"Magnet cleared our main drain line and scoped it with a camera to show us exactly what was going on. Honest, thorough, and priced well."
"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!"
"We noticed our water bill doubling month over month and could not find anything visible. These guys came out with the leak detection equipment and located a slab leak under the living room in about thirty minutes. The repair was minimally invasive — small access cut, patched afterward, and the bill is back to normal. Really impressed with the professionalism."
