Canadian Pipe

Hey
I can only find CSA (Canadian Standards Assoc) PVC Pipe and regular PVC. I assume this means its pressure rated, but how much pressure?

Probably not. Is there any other writing on the pipe? If so can you write it down for us, we might be able to check if it's rated or not.

Nova Scotia. I am near a Home Building Center, Home Hardware and a Canadian Tire. I asked the guy at the Home Hardware for pressure rated PVC and then he went from trying to sell me standard pipe to CSA pipe, he didn't know what the PSI rating actually was though. I believe it was sch40. If it matters 120psi would be an ideal pressure rating and the lengths would be 6ft of 4" and 6ft of 2"

Just because it says SCH 40, doesn't mean it's pressure rated.

You can always google the typenumbers or company names that are on the pipe. You should be able to find a few pdf's which tell their rating.
Especially when you know the standard they are made to. There are always sheets of data which contain information or requirements to the objects.


I once had unrated pipe, and after happily taking it up to 6 bar, I decided to google up the reading on the side.
Within 20 minutes, I found that the pipe was officially rated to 6.1 bar. :shock:
Which was quite funny in some way.

The "special" people that get hired to work in plumbing departments are required to NOT know their ass from a hole in the ground.

READ THE PIPE. it will have a either a pressure rating, or DWV printed on it.

Likewise with the fittings. DON"T ask, READ! The useable fittings WILL have NSF-PW embossed somewhere.

Here, even cel core ABS has a pressure rating printed on it.(IIRC 320Kpa on 4".That's around 50psi.)

No, not all pipe has that.
As I said I have encountered pipe with nothing more then a brand name and a bunch of numbers and letters which definitely do not contain a pressure rating or DWV.
