A » A gas water heater's pilot light may repeatedly go out due to several reasons, including a faulty thermocouple, dirty pilot tube, insufficient gas pressure, or a draft in the area. A malfunctioning thermocouple fails to signal the gas valve to stay open, a clogged pilot tube restricts gas flow, low gas pressure affects the flame's stability, and drafts can extinguish the flame. Professional inspection and maintenance are recommended.
