My natural gas bbq (NOT propane) no longer makes enough heat, so I've done the following: 1) remove burner tubes and ensure they were clear (they have spider protection covers and were clear 2) reassembled and ignited... VERY small flames came out of all 3 burners 3) removed flexible rubber supply hose and blew compressed air through... it was clear 4) reattached quick-connect from rubber hose to supply pipe but left the other end (to bbq) open, then turned on the supply line... very small amount of gas came out with almost no pressure.

My next step will be to purchase another shut-off valve and quick-connect, then turn off the gas to the entire home and replace these 2 items.

Does anyone have experience with gas shut-off valves corroding inside, or with quick-connect units failing? The shut off is a high-quality ball valve. There is a small pin inside the quick-connect but I haven't messed with it... do these sometimes fail? Any reasonable ideas would be appreciated.

HI Carlsbadbill...

What happens if you disconnect everything back to the shutoff itself? I would disconnect all back to the shutoff and then turn the gas back on and see how the gas flows then, OK? Let me know what you find...

Mark - Good idea... I'll remove the quick-connect from above the shut-off valve... and if the flow is good I'll know it is the quick-connect at fault. I'll try it late tomorrow and post the results. Thanks, Bill

Always appreciated!~

Problem Solved! The underground lateral pipe had rusted through in 8 years. The pipe was the proper green-epoxy coated 1/2 inch pipe, and the unions and street-L's were covered with the proper tape (although I don't know if they were properly primed). The problem was that the plumber who did the initial installation did not prime and tape the areas on the epoxied pipe that were slightly damaged by the pipe wrenches during installation. Such minor cuts on the coating led to complete rust-through in 8 years! Also, the street-L's were not quite taped completely, and the corrosion inside the small passages almost blocked them. Thanks for your reply, Mark.

Thank you for posting that information... very helpful, especially if you've installed the green coated gas piping. It shows just how important the small details really are with gas piping!

Thanks again!
