4" pipe?

[cwazy1]

So i cracked a fitting on my 2" chamber, and now, i want to go 4" instead of 2" because 2" was the only thing available at the time.

i know that HD and Lowes dont have it, i think my plumbing stores around here have it, but im not too sure. i have to call them tomrw, but what i hear is that mcmaster has it. i went on there and did a search thing and the only thing that came up was 4" white sch 40 pvc with a pressure rating of 130!. wdf so can someone link me to the "right" one i should be looking at?

Local plumbing supply stores should have 4" pressure rated pvc, mine was around 240psi.
