Common questions about water heater repair in San Mateo.
A water heater producing no hot water in San Mateo 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.
Rumbling, popping, or banging sounds from a water heater in San Mateo 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.
Yes. Magnet Plumbing services all major tankless water heater brands in San Mateo, CA — 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 San Mateo 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.
