EDIT- and yeah our lowes has it all sorted out on either side of the aisle


Just keep an eye out for black surburbans... :lol:

What is the difference between pipe marked "not for pressure" and the pipe which has a pressure rating on it? I'm not talking about cellcore pipe here; at my local Lowes, there is solid pipe marked "not for pressure". What makes it not for pressure, and what is the difference between it and pressure rated pipe?


It's just as you would think. The pipe marked "not for pressure" isn't pressure rated, and the pipe that isn't marked "not for pressure" is pressure rated. Now the reason for that I don't quite know. Odds are it has to do with the pressure rated pipe is used in the food industry to transport low pressure liquids such as drinking water, etc. But don't quote me on that. :?

i think it has something to do with the fact that non pressure rated pipe is manufactured using lower standards, and/or different techniques.

Wellllll.... the pipe that says "not for pressure" is not for pressure. You really don't give a rat's ass why it is marked "not for pressure".

BTW, the presence of "DWV" on a piece of pipe (or a fitting) means essentally nothing. It is not at all unusual to see pipe with both DWV and PW on it.

The important thing is that it says PW and/or has a pressure rating printed on the pipe. If that is the case then presence of "DWV" means nothing. Any pressure rated pipe can also be used for DWV. It is the converse that is not necisarily true.
