Does anybody know the pressure number (PN) of schedule 40 and schedule 80 PVC pipe commonly sold in the United States and Canada?
The PVC in my part of the world is classified by PN number, and I'd like to know which PN number is ideal for DWV applications.
I'm interested in finding out the pressure number that is equivalent to schedule 40 PVC. We'll be using 5 cm, 8 cm, 11 cm and 16 cm diameter pipes for DWV applications. Also, our climate is subtropical (i.e. warm) and the temperature does not go below freezing.
