I'm in the midst of a project and I was all set to go with 3" Schedule 40 fittings for the vent and drain pipes, but as you can see by the photos, the OD of the existing 3" pipe is slightly smaller than new standard Schedule 40 3" pipe that I was prepared to use. Is anyone familiar with the type of DWV pipe in the pictures? Are fittings available for the type of pipe I have or do I have to adapt the existing stuff to Schedule 40?
BTW - Thanks for this great forum.
