The point is that these pipes can and do rupture from any number of causes and when they do it can be catastrophic, 90 PSI in a 1/2" line is more than enough to cause serious injury. One incident I read about back in the 80's involved an eye injury when a guy bumped a PVC line with with a welding tank cart and another was when someone hit one with a fork lift. Arguing these accidents should not have happened in the first place and the lines should not have been in those locations is pointless because unless a PVC line is inside a shielding conduit (considered safe to do it that way BTW) then any number of unforeseen circumstances can occur. It's a fact that even a blow light enough to only dent copper line and not even scratch iron pipe could easily cause a situation like that ridiculous gunshot incident. The welding cart would have been an unnoticed non-incident and the forklift might have been a leak but neither would have been the injury causing accidents they were because of the PVC. Also PVC does not need a blow from a sharp (or even blunt) object to rupture and often the rupture is not at first apparent, age or deterioration from any of several common contaminants (or sunlight) can cause a PVC pipe to rupture without warning. Pointing to an old PVC setup as proof of safety is no different than pointing at a ninety year old smoker as proof that cigarettes are harmless, beating the odds is not proof something is safe.


I agree with you oldred... But isn't 90 % of the things we do everyday unsafe..Like cutting aluminum with circular saw,, It is unsafe,, But is done everyday... Riding down the road everyday is really unsafe,, Like using a cut off wheel on a grinder,, And so on.... The results from using pvc pipe is the same good and bad on anything... Am I saying to use it... NOT AT ALL !!!! But it has been done for years with good results as well as bad ones.... Kind of like driving your car.... It has to be done with commend sense..
Like anything..We do everyday...That's the only thing I can say on this..

Use what you want to.. But ''ALWAYS'' remember there can be a dangerous side to it..


There is a dangerous side to EVERYTHING...

I haven't read every word in the thread so forgive me if I repeat but the possibilility of failure isn't the only reason not to use PVC, it retains heat. You want your air to cool off so the water trap can do it's job.

And someone mentioned black iron pipe, NO, black iron is for gases without moisture. You want galvanized pipe, or copper of course.

I did my garage in galvanized in one afternoon, done deal never have to think about it it again, EVER.

Get real Oldred... If I had something against you... You would be the first to know it.... And I wouldn't do it in front of anyone... Now calling me childish.. That's a Act against me.... I think I have every right to say what does work in what doesn't also... I said: ''IT ISN'T SAFE''... Didn't you see that...


As far as the winning against you comment..I have learn in the pass that a lot of times it only your way.... Are is that your way of showing you have something against me???

there is a new plastic out that i am going to look into. depending on price i may replumb this winter. i believe a very big factor is pressure. even my 15 horse compressor at the van shop was set low. i had no doubt that thing would explode pipes. all i'm saying is it can be used safely if you pay attention and do it right. mine is run so it is protected , i run less than 90 lbs of pressure . i would love to do my shop in copper but the price is ridiculous. we're talking over a couple hundred feet of copper. we'll see what this new stuff is and the cost.

i promise red if mine blows and puts a splinter in my butt i will sell a cow to buy copper.....

Shine, copper isn't expensive at all! It isn't as cheap as PVC (pvc is damn near free!) but it isn't like brass pipe, now THAT is some expensive stuff! I did a short 18" section with a few elbows and it was $65!

But copper would only cost you $250-300 with all the fittings!

copper is around a 1.50 a ft here plus fittings. the 100 ft kit comes with 2 outlests with drains and a manifold . not a bad price.

No, I haven't used it, but my common sense tells me that it won't cool like metal.

I seriously doubt that you could cool the air inside of the pipe enough that the outside air temperature would make it sweat.

You have to keep in mind that you are not running cold underground water in the pipe, its warm air from the compressor.
