OK. I have to tie into a 3" x 2" cast iron fitting so I can run my PVC. I need to remove the 1-1/2" galvanized pipe which is completely cloged up that has been installed with oakum and lead then try to attatch a 2" PVC to the cast iron hub because I have a shower drain that must run into it.. I was thinking a fernco to do this though the supply houses say I cant because the fernco wont go over the outside the hub. My other option was to insert the 2" PVC into the hub and reset the oakum then pour lead around the PVC. I CAN NOT remove the cast iron without disturbing the downstairs walls which I really do not want to do.
Also what is the best way to install a PVC toilet flange into a cast iron fitting? I know they have those screw in type with the rubber gasket. I may use that with some duck grease on the rubber.
Any thoughts?
