I R a XT Plumber

Because cross connecting gas lines, like oxygen/nitrogen, can kill people.

Well duhhh. Again they test at a competent level just as I have and I’m going out on a limb here based on your comment but you did as well. So have you approved that type of cross connection or did your competency test prevent that, rhetorical question!

Not "all" plumbers employees are "licensed", just as most CM's lack licenses and trade experience (working under a GC's license who rarely walks their jobs)
Inspectors are often our only line of defense against them.

Did I write licensed or unlicensed. Read again and learn to think for yourself, stop being a cheer leader for Kyle B or anyone’s else for that matter.....
