Cut a piece off and look at the part you cut, if the pvc is solid, its good, if it is filled with lots of tiny bubbles its bad.

Sand of some paint until you know where the writing is then sand of the paint covering it, the paint will come of way before the writing does.

well if im sure its solid core and sch 40 then i dont need to sand the paint off right because it is for sure pressure rated right? if worse comes to worse ill just go to the store and check the stock they only sell 2 types of pvc so im bound to be able to find out.

Sch40 is only a thickness rating not pressure rating, most pipe with sch40 is pressure rated but some isn't you need to look for the nsf-pw rating, it should have a PSI rating and at what tempreture the rating is taken at.

But if you dont get it all off it could damage the PVC. I'd just go look at the shop.
