Running 1 1/2 PVC through studded wall - not flexible enough. Options??

We are moving our kitchen sink to a different wall. This will require me to run a new drain line through the studs and connect to the vertical drain. Since the PVC isn't flexible enough to run through the studs, is there another option. Ceiling below is finished and not accessible so that isn't an option. Does anyone make an acceptable flexible pipe?

I can't tell you how many houses I've seen where the PVC is cut into short pieces with a coupling between each stud or joist. It's not pretty but it works.

If you're not running through a load bearing wall, you could notch the studs. You'll need to cover the notches with steel nailing plates (but you'll need to do that anyway).

Just remember, drilling a 1.75" hole in a 3.5" stud very much reduces its load bearing capacity significantly.

Can you cut the kitchen floor, if that makes it easier?

Option #1 for me would be to open the ceiling below - assuming it's sheetrock.
Option #2 would be to use short sections and couplings.

IF you have the room to allow the required length to be beyond the starting point you MAY be able to cut out a short section of ONE stud and the push the pipe through pre-drilled holes in the remaining studs. You need to be sure to drill the holes such that the finished job will have the required slope for proper drainage. After installation then patch the cut stud.
