Water Heater Repair FAQ — Affton, MO

Have questions about water heater repair in Affton, MO? Start here.

Why is my water heater not producing hot water in Affton?

A water heater producing no hot water in Affton 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.

Can you repair my tankless water heater in Affton?

Yes. Magnet Plumbing services all major tankless water heater brands in Affton, MO — 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.

Why is my water heater leaking in Affton?

Water heater leaks in Affton 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.

How long do water heaters last in Affton, MO?

Tank water heaters in Affton 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.
