Lighting / Re-Lighting Your Water Heater
Tank-type gas water heaters use a pilot light to ignite the gas burner when the water in the tank needs to be heated. Usually, the first warning that your pilot light has gone out is the cold water coming from the hot water tap. A pilot light can go out for reasons other than equipment malfunction, such as unexpected fluctuations in gas main pressure. If your heater’s pilot goes out, you can relight it yourself.
