I need a recessed floor drain like the one described at Family Handyman here:
https://www.familyhandyman.com/article/laundry-room-plumbing-a-recessed-pvc-floor-drain/
Here's their assembly:
However, my 2" drain is ABS, and the sewer and drain adapter used in the above assembly isn't available at a reasonable price in ABS, so I thought this may work at least as well:
The exact same 2" drain, which just drops in, so PVC is fine:

Instead of the sewer and drain adapter, a
4" x 3" Hub x Hub ABS DWV Reducing Coupling:

Instead of the 4" coupling and 4"-2" reducer, a
3" x 2" Hub x Hub ABS DWV Reducing Coupling :

with a short piece of 3" ABS to connect the two reducing couplings.
Do you see any problem with this assembly?
