My house has an outdoor natural gas line (with a shut-off valve) which I have never used before. I recently purchased a natural gas grill and the quick connect inlet is slightly larger but has the same diameter (3/4 inch). I plan on using gas safe Teflon tape and paint the pipes with rust proof paint.
How safe would it be for me to swap this part myself? Would I need to shut off the main gas line or is keeping the shut-off closed safe enough? Besides a soap test, would I also need a pressure test since I do not know the condition of the pipes? Or is this a job best handled by a professional?
