[SEL] PVC air lines

[Mark Shulaw]

Hi,
  I can't tell you more then the web about CPVC.  Just that my 
experience is with CPVC and we have never had problems with it. Trust 
me we really would rather put in Black Pipe. (Not Galvanized!!) but 
if you are on a budget CPVC is the way.  I never tried Pex but it 
looks like its ok. I am not up on the modern water pipe but Pex is 
the stuff that comes on rolls? If so I would think it would not be as 
nice to work with as far as keeping it straight. We do not want 
bellys in the lines to gather water. CPVC stick is easier to put up 
and keep straight with support. If I were not putting up black pipe 
it would be CPVC.
  I do like the thought of copper and polishing it up. GRINNN  Just 
too expensive.   I know a fellow engine collector from New Jersy that 
when he discovered the exposed water pipes in his houses crawl space 
basement was copper he polished it all. Sure was perdy. Yah gotta 
understand this fellow he is a clean, neat and tidy freak. As well as 
being a details fellow.                   TTYL,    Mark
