Answers to frequently asked water heater repair questions from Altadena homeowners.
A water heater producing no hot water in Altadena 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.
Rusty or discolored hot water in a Altadena 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.
Water heater leaks in Altadena 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.

Real feedback from homeowners who trusted Magnet Plumbing with their plumbing projects.
"Called Magnet Plumbing when our old 40-gallon tank started leaking. They came out the same day, gave me a fair quote on a tankless replacement, and had it running by end of day. Could not be happier with the work or the price."
"Amazing work. Good people. Reliable. On time and efficient. And prices are definitely hard to beat! HIGHLY RECOMMEND!"
"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."
