Am making an accessory apartment out of my garage ,would love some help on laying out the rough in pvc drain lines.
The apartment is a kitchen sink then a wall,tub,toilet and bathroom sink all pvc under the garage floor... then through the foundation to pick up the main 3" pvcpipe witch goes into a 4"pvc pipe.

You have to provide the drawing of the rooms and existing plumbing first, or anything we do is a shot in the dark.

So you are willing to trench the concrete floor? All drainage needs pitch and we have no idea how far you must run to connect to the 4" line. The 3" line that connects to the 4", what is it draining already?
