I'm installing a dishwasher from scratch. The only place to put it is in the breakfast nook off the kitchen. I've already successfully installed the electric. Next, I need to install the drain and water feed line.
I would like to pass the plumbing where the red x is. The plumbing will be a braided stainless steel water line and a flexible drain line. I would also like for the lines to be serviceable after the fact.
My best idea is to embed a 1.5in or 2in pvc pipe in the wall. Glue the pipe to the lath in the wall and then fill the gaps with joint compound.
Is this a good idea or is there a better way?

Dishwashers don't require a full size drain. There is no need to run a DWV line to your dishwasher.
They drain through a 5/8" or 7/8" flexible hose that attaches to the sink tail piece or the food disposal unit.
They fill through a 1/2" feed line.
You shouldn't need larger than a 1 ½" hole through the wall into your cabinetry and then run the lines in the back of your cabinets. I think you will want to go lower though since your drawers probably go all the way to the back of the cabinets and anything mounted there would keep them from closing.
Have you bought the DW unit? If you have it, check the install instructions and the feed and drain line sizes.
