The only problem I've got with that statement is that it doesn't come with a pedigree. More to the point: PVC is impact sensitive. How do I know some dolt at the PVC factory didn't drop that piece of pipe? It *should* be able to handle everything, but since he dropped it there are now microcracks... blah blah blah.
PVC gives me the heebie jeebies.
Exactly. I've had 260PSI rated PVC blow at 110psi for no apparent reason. It will be made in the same fashion as in America and from the same stuff. It may not happen often, but once was enough to make me cautious when using PVC even if the rating boasts a 100PSI+ difference.
