Hello All!
I am attempting to tackle the replacement of my 1950's bathroom steel drain pipe but I have a few question before I start.
1. Can I cut off the vent pipe above where it stubs out of the wall without worries of the pipe getting damaged in the attic or falling because of the lack of support from the rest of the connections?
2.If I can cut the pipe will I be able to use a Fernco No-hub connector to attach the vent to the new pvc T?

Thank you
Brian K

I think the pvc T will need a short piece of pvc pipe added, to be compatible with the diameter of the no-hub fitting that will also fit the old metal vent.
