True sizes for ABS and PVC pipes

[Twowaxhack]

So they are for egress rather than supply. Can't use them for water supply right?

You can use pvc pressure pipe outside the foundation for potable water supply in my jurisdiction.

I have a charts on PVC and ABS in the first post. Are you looking for different sizes not listed there?

Is there a difference between sch 40 and DWV PVC?

They're both made from the same form of unplasticised PVC (PVC-U) but the difference is in the wall thickness. Schedule 40 PVC pipes are made with thicker walls that stand up to low pressure applications. Whereas PVC DWV piping has thinner walls and is not made for pressurized applications.

Thank you!
