For drains plastic is much noisier than metal. My preferred solution is
cast iron for drains and copper for potable water. For plastic I like
schedule 80 PVC. Some will favor PEX.

Anything else to consider?


It's easier for a typical homeowner to rework/repair down the
road. You make your new joints with liquid adhesive, not a torch
and solder.
