Cracked cast iron 4-way Tee in Vent stack/sewer drain in bathroom

Quick summary: weve 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 Im attaching, youll 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!

Hmm not good. You're in for a project. You'll need to replace the entire fitting. The cast iron stack that goes through the roof is extremely heavy. Potentially very dangerous and/or lethal. You'll need to make sure it's properly secured with a riser clamp on the roof to keep it from shifting or falling before trying to cut or remove the fitting.

Is the picture you posted upstairs, downstairs, main floor, what?

I think I'm calling in the troops, in other words, my loyal plumber, to correct the problem. He'll have all the proper tools, insurance, etc.,,,.

I have my business to run (my dad & I own a couple of ACE Hardware stores), and Scott has a plumbing business to make a living with! Sure, I could probably get the project done in double the amount of time, but I have business to take care of here @ the store.

Here's a better picture of the cracked pipe.
