DWV fittings compatible with SDR pipe?

[P5200]

I have (I think) what is a 4" SDR pipe sticking out of ground that I need to adapt to a 3" DWV pipe coming from a toilet. Was wondering, if a 4"DWV coupler will fit the 4"SDR pipe coming out of ground. I know I will need a 4" X 3" reducer coupler I have a 4" DWV 90 degree elbow also. It's really tight space under a mobile home. Thanks!

A thin wall drain fitting will solvent weld into a sch 40 fitting.

I got a measurement on the thin wall pipe coming out of the ground and it was right at 4/ 1/8" OD the sch 40 elbow has a lot of slop when I slip it over the pipe. Would I maybe, need something like this adapter? NDS PVC Adapter, 4 in. DWV/SCH40 Hub X S&D Hub 3P16 (homedepot.com)

yes, or you can glue a thin wall fitting into a sch40 fitting. Same difference.

I'm not sure, I'm fully understanding but will one end of this coupling fit over the 4" thin wall pipe and the other end fit inside the sch 40 elbow? Thanks! NDS PVC S&D Coupling, 4 in. Hub X Hub 4P05 (homedepot.com)

Hi, one last thing I need to know is what I would need to adapt my 3" thin wall pipe from toilet to my 4" sch 40 elbow? Thanks!

I guess, I could maybe put a short piece on 4" sch 40 pipe in the elbow and then maybe, adapt to that instead if possible. I just hate to spend $18.00 for a 2 foot piece of pipe when I only need 3 or 4 inches worth. Thanks!

I wound up using a 3" thin wall elbow with a 4"X3" thin wall adapter. Thanks for all the help!
