To relight a gas water heater, always check the side of the water heater or your owner’s manual first for step-by-step instructions. The manufacturer will typically advise you to:
Turn gas valve’s dial to “Off” and wait before relighting pilot.
Before doing any maintenance on your water heater yourself, be sure to shut off the power, and read your owner's manual.
You should also periodically inspect your water heater burner. The flame under the heater should appear blue with yellow tips. If it’s mostly yellow, or if it’s sooty under there, your flue may be clogged, which is a dangerous situation. Contact us to check it out.
We recommend having your water heater inspected by a service technician every year. He or she will also check the drain valve for signs of leakage, and the anode rods for corrosion.
