What O'Fallon homeowners want to know about water heater repair — answered by our licensed plumbers.
A water heater producing no hot water in O'Fallon 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.
Water heater leaks in O'Fallon 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 O'Fallon 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.
Rusty or discolored hot water in a O'Fallon home usually indicates an anode rod that has been depleted and the tank is beginning to corrode internally. In some cases it is sediment stirring from the tank bottom. If the unit is over 8 to 10 years old and producing rust-colored water, tank replacement is often the recommended solution.
