I have a Richmond, Direct Vent, 50 gallon water heater and the pilot light likes to go out once or twice a month. I usually find out when I am standing in the shower and find I am showering with 80 degree water. So what have I done. Several months ago I sprinkled pixie dust on the problem and replace the igniter and flame sensor unit. It seemed to help for about three months and then the problem came back. I can not believe the unit has gone bad again. relighting the water heater is easy. I only push and hold the button down for a couple of seconds, hit the spark, look down to make sure it is lit and let go of the light button. ( then turn it on) It would seem if the pilot and flame sensor was an issue I would have trouble relighting. What are the chances the gas valve is the problem or is it possible that the main burner shutting off is blowing out the pilot. I know many of you have run across this problem and have tricks to fix it. The water heater is only 6 years old and the tank is in great condition. Suggestions please. Peter I had the new igniter / flame unit out last Saturday - checked the pilot orifice, main burner and did not find any loose rust that would block the pilot gas line, or loose debris on the main burner.
