I'm having similar trouble with my WH in an original '77. I have changed out the thermocouple assembly but don't know how to go about cleaning the gas line. Is there a chemical that I could introduce from the tank end? Any suggestions would be appreciated.
It was fine for the first tank last weekend, but the pilot went out and wouldn't stay lit. Changed over to the second tank, but no-go. Changed out the thermocouple (both parts) and still can't keep the pilot lit.
