Why The families on the DWV Folder inside PVC have both Sch 40 and DWV in the name ?

[Caed9]

Hi I'm Currently trying to set up routing preferences on pipes. I'm trying to understand the different kinds of PVC pipes. What I found is that sch 40 and DWV should not be mixed. So When I try to load the families for DWV, they have Sch 40 on the name as well, its kind of confucing. So in Revit this families can be used for multipurpose in PVC in general, including for CPVC, and Sch 80 respectively?  Is just the naming? I can simply rename them to match the usage, or are there additional settings that should be changed as well?

I don't do US imperial systems but I assume its based on the Charlotte pipe type:

" So in Revit this families can be used for multipurpose in PVC in general, including for CPVC, and Sch 80 respectively?" - I don't think you would use it for schedule 80, surely for that you need schedule 80 pipe and fittings?

Well I'm just researching PVC and found that sch 40 is used in residential and 80 is used for commercial and mostly for pressurized water supply, and DWV is supposed to be a whole different thing as it is not capable of handling supply, as it stands for draining, vent and waaaste. but now I'm confused cause that schedule states that DWV is the same as Sch 40, or what I understand is that DWV has its own sch 40? I'm just trying to figure it out.

As I said, I don't do US imperial systems.

Someone in USA would be better placed to advise.

It is called SCH 40 -DWV PVC, to differentiate from another type of PVC pipe that is allowed in some jurisdictions otherwise known as "Foam-Core PVC"...  They are dimensionally the same and look the similar from the exterior ,however the foam core wall is not Solid PVC.... it's foam. Hence it is lighter and has no pressure rating.

If you buy SCH 40 PVC, it can be used in pressure applications or for drainage applications, it's simply dual marked as Sch40/DWV.
