I don't know if this is appropriate for this board or not, but I figured that most plumbers have some experience with gas lines too. Anyway, I have a commercial natural gas stove with a pilot on each burner (6 total). The pilots slowly get lower and lower over several months until they refuse to stay lit. I took out one of the pilot lights and cleaned out the supply tube for it with an air compressor. I had a bunch of black material come out. Since then, that pilot has been working great.
I've got a feeling that the offending foreign material might be coming through the supply line. The lines are quite old. Also, there was some recent construction work that had to connect to the existing lines. Does anybody know of any in-line natural gas filter I can put in place before this stove in case this is the problem?
If anybody has any other ideas on the source of this black material, I'm game. My initial instinct was it was carbon buildup, but wouldn't that be at the pilot tip itself and not back in the supply tube?
