Answers to frequently asked water heater repair questions from Derby homeowners.
A water heater producing no hot water in Derby 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 Derby, CO — 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.
Water heater leaks in Derby 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.
Water heater repair in Derby 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.

Our reputation is built on results. Here is what our customers have to say.
"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."
"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."
"They are the best. They come when they say they will, fair pricing, are attentive to detail, protect the floors, are friendly and professional. Very different from plumbers we have used in the past. Thank you Saul!"
