i wouldnt go over 150. the pipe may say higher, but things like the heat/cold and the sun and other factors decrease the max pressure.

you could get away with what ever the ratting of the pipe is, but i would say 150 to be safe.

It has dwv elbows. DWV isn't rated so I wouldn't take it over more than 60. Even then I'd be scared.

In my experienced opinion, due to the dwv fittings max would be 50 psi. However, even that is pushing it. You should just not use it at all.

key sentence "after i replace the fittings and elbows...Ik what i have on it right now is the wrong ones, im going to replace them with pressure rated..

:roll: i swear some people dont read the posts right. :roll:
