Frequently Asked Questions About Water Heater Repair in Defiance, MO

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.
Most new standard tanks come with a 6 to 10-year manufacturer warranty on the tank and parts. Tankless systems often feature up to a 12-year warranty on the heat exchanger. We also back our installations with a labor guarantee.
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 a standard family of four, a 50-gallon tank is usually sufficient. If you have a larger family or a high-demand roman tub, you might need a 75-gallon tank or a high-capacity tankless water heater.
