    Had the plumbing roughed in when house was built and finally thinking about finishing basement. The shower drain is cast and below grade. I need to move it about 2 feet over. Looks like the have a donut fitting going from main4 inches to 3 inch bell. Ptrap is under slab since it holds water. Can I remove the cast fitting and put fernco donut in to change to pvc? If so do they sell 4 to 2 pvc reducer? Do I need to move ptrap to be directly under shower drain? Let me know your thoughts I have attached 2 pics. The drain and the other is the vanity drain which the plumber leaded the pvc to cast.

    Your code might not allow pvc under grade. The trap needs to be directly under the drain.
