Copper is expensive and thieves love it. It might not be to bad if it only needs a little ran in a small shop but when it needs to go 100ft to the other side of the shop it might start getting expensive quick.
My boss has sch 40 3/4 PVC which is good up to 480 psi ran in his shop. He told me its been there for over 30 yrs without any problems. His son has painted many a car with PVC pipe.
I have always wondered about the 1/2" copper versus the 3/4" PVC in far as volume. Seems like the 1/2" copper would not produce as much volume but I'm not a expert on these matters.
Oh... PVC won't show up on X-RAYS so the doctor can dig it out of your body. lol
