Emergency Water Heater Repair
A water heater can fail in a way that costs you hot water for a day. It can also fail in a way that floods a closet and soaks the drywall behind it. Knowing which one you have matters.
Call right away if you see water pooling around the base of the tank, rusty or sandy hot water, a popping or rumbling noise that never stops, a burning smell, or water running from the relief valve pipe. A tank leaking from the body will not seal itself, no matter how many times you dry the floor. Shut off the gas valve or the breaker, close the cold water valve on top of the heater, and call.

No hot water by itself is usually not an emergency. On a gas tank, the cause is often a failed thermocouple, pilot assembly, or gas control valve. On an electric tank, it is often a burned-out element or a tripped breaker. Both can be tested and identified quickly.
Tankless units tend to shut down and show an error code instead of leaking across the floor. Ignition failure, flame loss, and overheat codes are the ones we see most. A blocked vent, a dirty flame rod, low gas pressure, or mineral scale inside the heat exchanger can all trigger them. Brea's hard water makes scale a common culprit on tankless units that have never been flushed, and it shortens the life of a conventional tank by coating the bottom with sediment. We check the cause before we quote parts or suggest a replacement.
