Thankx...Ok thats what I thought. But 4"?! isnt that a pain to seal tight enough to stay pressurized. Do you have plumbers wrenches that big? OR just allot of teflon tape would work too.

But just one last question? I have a length of 4" PVC (my brothers a plumber I get scraps) I dont have it in front of me now but i am sure it was rated for 150PSI or around there. Is 4" not safe to 125PSI? I noticed you stopped at 50 PSI. Why?

It's probably rated for a bit more than that. Most schedule 40 stuff is rated at ~220 or so.

As long as it has a pressure rating on the side and it does not say cell core you are fine. And the reason I stay around 50psi becuase the fittings are DWV.
