  • Rusty or discolored hot water

    This often means the anode rod is depleted or the tank is corroding. In Mission Viejo's moderately hard water, anode rods wear out faster. If you see rusty water, call us before the tank fails.

  • Popping or rumbling noises

    Sediment buildup on the bottom of the tank causes popping sounds. This reduces efficiency and can lead to overheating. A flush can often solve the problem.

  • Water pooling around the base

    A leak from the T&P valve, drain valve, or tank seam is a serious issue. Turn off the power or gas and call us immediately. We offer emergency Water Heater Repair Mission Viejo CA.

    A faulty thermocouple or dirty pilot assembly is usually the cause. This is common in older Mission Viejo homes. We can replace the thermocouple and clean the assembly.
