Answers to frequently asked water heater repair questions from Cranbury homeowners.
A water heater producing no hot water in Cranbury 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 Cranbury 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.
Rumbling, popping, or banging sounds from a water heater in Cranbury 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.
Rusty or discolored hot water in a Cranbury 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.

"I called many places to see if someone could come and install a much needed commercial sink at work. Saul called me back and said he could be there in a few hours, and 3 hours later he showed up and installed the sink, faucet and replaced a broken toilet we had."
