Alternative to Ground Joint Unions
I am "doing it myself"....I am plumbing 2 inch steele pipe into a building on my property. It is for natural gas.
The line from the meter to the inside wall of my building was done by a pro.
It comes in the shop about 6 inches off the floor amd goes up about 9 inches.
From there I have a UNION ( I can not spin a 90 because I am too close to the wall). after the UNION, I turn left, until I reach a second UNION. (It was SO MUCH simpler to contruct my manifold on the pipe vice and then install it than to put in all on the wall piece by piece.)
But now I find this item that relates to my area:
"Special instructions: Do not use ground joint unions except directly at the meter or after the shutoff valve at the appliance. Each place where you will have a gas appliance must have a gas **** in the open position, capped off. You are required to provide a test of the system for the inspector"
So....what are my options? Do I take it all apart, then replace the UNIONs with regular pipe (forcing me to cut into the wall to rotate the 90)?
I've "heard tell" of some fancy thing-a-ma-bob which would thread into the 90, and would give me acces to LEFT HAND THREADS....I could then get a piece of pipe cut to length and have LEFT HAND THREADS cut into one end (cutting RIGHT HAND THREADS into the other end), then as I rotate the pipe the right hand thread feed into a coupler whilst the left hand thread feed into the insert.
Is this true? Is this not a "DIY" issue?
I can't figure out how I would cut L-H-T anyway....
Should I just call a pipe fitter?
Thanks,

There is a right-left coupler made but many local codes do not allow it any more.
Maybe your looking at this from the wrong end...How hard would it be to build from the manifold out to the union at the meter?
I usually shy away from giving answers to gas questions on this forum but you caught me on a good night.
Good luck and double check your work before you "fire" it up....
