Quick summary: we’ve had a leak behind the bathroom wall from where the kitchen drain ties into the bathroom plumbing to reach the sewer drain pipe.
From the picture I’m attaching, you’ll see the galvanized pipe coming from the left wall; I have successfully removed that pipe.
The big issue is that when I was trying to remove the galv pipe coming in from the right side, the cast iron 4-Way Tee cracked off as I was just beginning to get the pipe to start to unscrew.
It appears I will now have to cut out the 4-Way and replace.
Do you have any advise or tips on how I should proceed?
Thanks so much!
