Is flexible (but smooth-interior-walled, not accordion) Schedule 40 PVC pipe to code in PA for a residential sink drain? It would go inside the wall and replace an elbow. Otherwise the drain is normal.
I have no idea what kind of pipe you are referring to that could make a short radius bend. The list of approved materials is by ASTM specification, which must be on the pipe.
