Here is my huge problem. Last Nov my water heater let go. We replaced it and about 2 weeks later the pilot started going out every few days. We replaced it again thinking it was a bad unit. The new one did the same thing. We called gas co and they checked pressure and all was fine with gas. We replaced it again. Same issue 2 days later.
We thought it must be the batch of heaters, so GE sent out plumber to replace all parts of heater. Worked for a few weeks then started going out again, checked to see if chimney was clean and it is.
My carbon monoxide detector goes off when heater pilot goes out so I assume it must be a venting issue. It came with a 3inch hood and is connected to a 3 inch pipe to chimney. Is it possible that I need a 4 inch vent pipe and hood? This is making my life crazy and no one seems to know what it is. Help!!!! Please…
