appear in rec.crafts.metalworking the following:

Bob..at least once a year, I get called in to replumb a shop that had
PVC pipe that decayed due to compressor oil, heat etc etc and finally
blew out, often taking entire banks of florescent lights off the
ceiling, blowing **** everywhich way etc.

Im not telling you not to do it. Ive seen some up for as long as 10
yrs with no explosions. But each and every piece Ive taken down had
the structural composition of a grahm cracker. Drop it from 3 feet
and it shatters like glass.

Sounds like a shop which was plumbed for air with PVC pipe is like
the guy who was told smoking cigarettes was bad for his health. "I
don't know, they haven't killed me yet."


I don't recommend it, I have switched to PEX for impact resilience, but I
have at least 100' of 1/2 and 3/4 white PVC that is at least 25 years old,
without issue.
