plumbing
I am getting ready to close up my new kitchen soffit and I was wondering what would be a good option to try and soundproof the DWV pipes in the soffit.
Should I try to wrap them?
Or should I try to stuff in some Rockwool?
Or should I try to build some kind of box with acoustic foam?
Or do nothing and just accept some of that noise?
You'll need to install a drain assembly. In a bathroom, pop-up drain assemblies are common.
Here's an image of the drain assembly, with all the parts labeled.

The tailpiece of the drain assembly, should attach to the trap assembly. If the trap is too low, an extension can be used.
When installing the drain, put a bead of plumber's putty around the drain hole of the sink. Then bed the drain flange in the plumber's putty. From below, install the washer and nut, and thread on the tailpiece. When you tighten it down, the excess plumber's putty will squeeze out. Use you finger, or a rag to remove whatever oozes out.
The best recommendation when you cannot get any satisfaction from the building owner / manager is to MOVE to another place. When you rent it is not your place to be doing things like getting in a professional to work on things like the plumbing.
If you do get ready to move now you know some more what to be looking for and asking questions about before you commit to the new abode.

I can't imagine there would be a lot of noise coming from them. If you're really concerned about it, stuff some extra insulation up in there and and use 5/8" drywall or double up on the 1/2" drywall. I've done this in the past and had some pretty fussy customers happy.
