Answers to frequently asked water heater repair questions from Harbor Island homeowners.
A water heater producing no hot water in Harbor Island 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 Harbor Island, WA — 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 repair in Harbor Island 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.
Tank water heaters in Harbor Island 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.
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."
"Great job! Definitely recommend to others. Quick response, professional work, and fair pricing. Would use again without hesitation."
"Our older boiler was making banging noises and losing pressure. The technician diagnosed a failed expansion tank, replaced it, and the system has been silent ever since. Reasonable rate and quick turnaround."
