You might want to tell him to rip that pipe out, while you are there.
It is lethal when it blows, which it will do, eventually. I'd wear a
helmet when I visit, if I were you.
"Dear Mr. Cannova:
In response to your recent inquiry concerning our regulatory position on
the use of plastic pipe for compressed air systems, I trust this letter
will clear up any confusion over the issue.
It is our position that PVC pipe shall not be used as a means of
transporting compressed air. This position follows the manufacturer's own
statements that PVC is unsuitable for compressed air systems. We do allow
the use of certain ABS materials that are specifically designed for
compressed air systems. One such product is "Duraplus" air line piping
system ABS pipe. However, as in any such system, the manufacturer's
specifications on acceptable pressure and temperature considerations must
be followed.
In closing, misapplication of a product, such as using PVC for compressed
air systems, may result in citations and penalties being issued dependent
upon the specific conditions."
