Frequently Asked Questions About Water Heater Repair in Diablo, CA

A standard traditional tank water heater generally lasts 8 to 12 years with proper maintenance. Tankless water heaters have a longer lifespan and can often last 15 to 20 years if they are flushed annually.
No, a leaking Temperature and Pressure (T&P) valve means there is either excessive pressure inside the tank, the temperature is dangerously high, or the valve itself has failed. This is a safety issue that should be addressed immediately.
For an electric unit, a broken lower heating element means only the top half of the water is being heated. For a gas unit, the dip tube that directs cold water to the bottom of the tank might be broken, mixing cold water with the hot.
A pilot light that repeatedly goes out is usually due to a bad thermocouple. The thermocouple is a safety device that senses the flame; if it fails, it shuts off the gas. Call (877) 415-0636 and we can replace it quickly.
We highly recommend flushing your water heater once a year. Regular flushing removes sediment buildup, which protects the inner lining of the tank, improves energy efficiency, and extends the life of the unit.
