Ulcers most commonly occur on the inside of the mouth but may also occur on the tongue and lips, or in association with more generalized conditions, such as cancer. Allergic reactions to food and other substances may cause inflammation, swelling, and development of mouth white patches.
Part 3 Relighting the Pilot Light. 1. Turn the gas valve to the Pilot setting and push down on it. Doing this starts the flow of gas into the tube that supplies the pilot light. If your water heaterâs gas valve does not push down, look for a red control button near the valve. Hold this button down.
The pilot is a small flame that ignites the gas burner on your waterheater. When it goes out, first try relighting it, following the directions on the water heater label. If the pilot doesn't relight, or if it goes out right after lighting, by far the most common cause is a bad thermocouple.
