Hello. My mother-in-laws pilot light on her hot water heater keeps going out. I have had to light the pilot three times in the last couple months. The heater is about 8 years old and looks really clean around the burner and thermocoupler. She states that it usually goes out only when it is extremely windy outside. I checked the flu and it appears to be clear and hooked up ok. Is there something on the flu or the hot water heater that would allow high winds to blow the pilot light out? I did notice one time I lit the pilot light the wind was blowing through the water heater and kept blowing out the matches. Any ideas? Thanks in advance!
