Mike. I used HOT water pvc. 1/2 inch. I think it was rated at 600psi. I
glued all joints. Ran 2 outlets in garage and 2 in basement and one out
side. Did this about 5 years ago. Long run to basement is about 70 feet.

The psi rating is for water, not air. Water is not as expansive and does
not explode like a gas under pressure. If the pipe is not rated for air, it
should NOT be used. There have been some rather explosive problems with PVC
air systems and it is not allowed by OSHA and some other building codes.
The fact that you'd gotten away with it for now, does not mean it won't
explode into shards.
