The original main stack in our 1907 remodel is 4" cast iron hub & spigot. The topmost segment's hub is damaged so I either have to cut the pipe back or remove the topmost segment to get back to an intact hub.
What is the best way to connect a new 4" cast iron NO HUB building drain to the old hub & spigot stack at the perimeter wall?
(Also assuming I have to remove the topmost segment and get back to a clean hub... how best to accomplish?)
Thanks!
