Hi, I live in San Diego and just bought a house built in 1986. I am talking to plumbers about hooking up a gas grill in my backyard. The original owner stubbed for natural gas by running a 3/4" black iron pipe (wrapped per code back in the 1980s) under a concrete patio. The pipe comes up about 15-20 feet behind the house (in the perfect spot for the bbq). The previous owner guy never actually used that pipe, and so it has just sat there all these years. My plumber is telling me that if it passes a pressure test then it should be safe to use (although he doesn't believe it will pass based on its age). There is some rust that can be seen at the house end and again at the stub end.
I am trying to figure out if I am asking for trouble by using it (even if it passes the test). I'm especially worried because a different plumber I asked to look at the pipe said, "Well, that is old black iron and not suitable for outdoor use like that...nowadays the pipes get dipped not just wrapped."
It would be pretty expensive to run a new line and so my alternative is probably to cap the existing gas line and start using a propane tank for the bbq. Of course, I already own a brand new gas grill and the manufacturer (Lion) tells me you can't convert a Lion grill to propane by just switching the orifice. They suggest switching out the gas grill to a new propane grill, but of course the company that sold me the grill at the Del Mar Expo won't even return my phone call.
I'm about going crazy here so any thoughts from the pros would be appreciated.
