[SEL] PVC air lines

[Judge Tommy Turner]

Schedule 80 plastic (the gray colored stuff) is pretty heavy duty.  The
air compressor I have in my shop is a big Campbell Hausfield.  100 gal
tank, 10 HP electric motor (that is huge, not one of the "small" motors)
and a big cast iron 2 stage compressor.  It was bought for an industry
and they never installed it.  I bought it and put it in the shop.  It
kicks off at 165 psi and on at about 135.  I can put a 1/4 inch air
chuck in it and let the air flow freely out of the hose.  It will kick
on, pump up and kick back off.  Its great for sandblasting.  I had my
old shop on this compressor and had the whole shop plumbed with the gray
schedule 80 pipe, probably 150 ft.  It lasted for 12 years before the
tornado got it.  I never had a problem with it in any way.

Yup is sure does say that. I never said the manufacturer recommended 
it for compressed gases. The manufacturer never intended or rated it 
for compressed gas so they have to say never for liability reasons. 
But we have seen it done for years and I have put it in my own 
shop.   Bill did express some concerns over cost. Sweat copper is 
easy if you know how to sweat but expensive.  I think black pipe is 
cheaper but involves a lot of cutting and threading, that for someone 
who has not cut and threaded is a daunting task and has a good bit of 
skill involved to do it without breaking something. Plastic is the 
cheapest way I know to plumb a shop.  And if its laid out right it 
works well and if its braced well around the outlets I have never 
seen it fail.
  I seen a suggestion to run the main trunk line in plastic then 
drops with black pipe. I've seen that done too and its a great 
compromise idea and eliminates the hose tugging and bump 
risk.                 TTYL,   Mark
