Hello, I am new to the forum and I have a predicament that I'm hoping to get some direction on. I am in the process of renovating our upstairs bathroom in our 1910 home, including running new plumbing. I am running PVC for the DWV lines and need to connect them to the existing Cast Iron main drain. Currently there is a Cast Iron 90° hub (3") with a smaller 2" line that T's off the front. The 2" T has a lead & oakum seal that connects to a small (1.25") steel pipe. My plan was to remove the lead & oakum seal, along with the small pipe, and use a fernco to connect my 2" PVC to the 2" part of the hub. This has proven to be quite difficult, to put it mildly. My question is, should I continue to pursue this option or should I cut the 3" Cast iron pipe further down and replace the entire hub with pvc? I assume it is 3" pipe. It measures 4" on the outside.

I will try to include a couple pictures for a frame of reference. Also, the cast iron pipe goes horizontally through the exterior wall and then, outside our house, goes vertically to the ground and ties into the septic.

I would cut it further back to avoid anymore frustration
 
Ok, thanks for the advice. As far as cutting the cast iron, would I need to rent a cast iron pipe cutter or could I get by with a sawsall?
 
If you use a sawzall make sure you get the right blades or you will burn through them.
 
Awesome, that sounds like a plan! I sort of wish I had pursued that option from the start, but I guess you live and you learn. Thank you both for the advice.
 
Update: I bought a cast iron specific blade and cut the pipe roughly as indicated in frodo's suggestion. Now I just need to go pick up a bit of 4" pvc pipe and I can glue it all together and move on!

wait.....put that can of glue down and back away from it.....

couple things here.

that 2'' tee can not be used in that position.......

the band on the cast you are using ........ that is a fernco...it does not hold the pipe ends square to each other
it is going to glog with toilet paper

what is that 1 1/2 catching ? if you use 1 1/2 on a tub drain, your drain will gurgle and drive you nuts


what is that 4'' tee on its back catching ? if it is a drain...... tees can not be on there back for drains

they are a fitting that is used in the vertical position
