PVC and Compressed air

[Southern Man]

Southern Man... you are a disgrace to all engineers.

Actually, your analogies are all invalid. There are plenty of old structures that don't meet current specifications and are performing fine. In fact, many current standards are designed using these as an empirical basis. As one who claims to have experience, I'm surprised that you don't know that.

Can you say, "I've adopted an indefensible position?"

[Southern Man]

Sure you can. You can also say something derogatory about corn mash.

[Redwood]

No need...
Your doing great on your own...
Keep talking....

[Southern Man]

Gotta love the guys who "know the code" but don't have a clue about the engineering principles behind them. In their minds they are never wrong.

Like the fact that air compressors have a tendency to have a small amount of oil from the compressor in the air and many of these oils have proven to adversely effect PVC.

The only compressors that would not have this oil in the air would be a much higher quality than what you have in your garage...

It's great that you know more than the engineers at Charlotte pipe but I'll stick with their advice...

Here's your shovel keep digging!

I'm not going to touch the whole PVC debate since I will admit that I don't know enough to say if PVC will degrade...

Personally, I would not trust all those glued PVC joints not to have small air leaks.
And then there is whats called "the creep rate" of most glues.

However as I said before there are other plastics that are approved for air lines and, as I understand it, the original poster just wanted a cheaper solution than copper or steel.

So back to the original question.
1. Yes it is possible to use a plastic pipe, but you have to use the right type.

The original poster wanted to use PVC because he already had it, not because he wanted any other type of plastic. We gave him the recommended answer. What he or anyone else does with it is beyond our control.
