I have a gas hot water heater and occasionally the pilot lite goes out and I re lite it. It keeps going like this for about 3-4X in a week then it says lit and its good for about 6 months then again it starts. When the pilot light goes out the water starts to leak out the drain plug? I know I should get a new one but I was hoping to just figure out this one. Thanks for any help I can get? I did google it but didn't get a laymans answer.
