Purging gas line


I just installed all new gas lines. I spoke with the inspector yesterday, and he told me just put a gauge on it and make sure it holds 5-10 psi for 10 minutes.

The pipes I bought are kinda dirty, and I used a lot of pipe dope. (when I say pipe dope, I mean specifically a can labeled for use with LP gas)

So, I'm just asking about the purging process. Should I remove the caps on the drip legs and provide continuous compressed air for a while, or is there a specific procedure you guys use to purge any crap/extra dope out of the system?

I'm convinced I got probably a small amount of dope into some of the fittings/t's because I went a little crazy with it.

Purging gas line


purge the pipes by attaching a vacuum pump to the lines and removing any contaminants
