Remove Steel Pipe in Cast Iron Base

[abdullah]

In the bath tub. In the concrete slab is a steel pipe going into a cast iron base. I want to replace this Steel pipe with ABS. This steel pipe has an outer lay or part of another pipe around it that rusted away. You can see what is left of the outside pipe at the base of the cast iron.

Should I remove the steel pipe totally? how would I do that. it looks like its welded in or something. I don't see any threads

Also if I cut near the cast iron base and put a fernco. Will the steel not eventually rust away also?

You need to use the "Upload a File" to put pictures in your post or a link to an external server. BUt, it's better to upload them so they don't disappear later if your server changes.

Once we can see what you have, you have a better chance of getting an answer.

If the steel is threaded, that's one thing. If it's leaded in, that's another. Need to know. Unless it's underground, you must used a banded coupler.

Sorry I uploaded the files. I will try to clean up the cast iron and see if i can better pictures of the cast iron base. Pictures are uploaded now.

I've been there. The no hub type coupling did the job fine. It did not get inspected so I don't know if there would have been a problem. If you have to unlead the joint and fit a donut, the job is much more difficult and unpleasant. The small area of galvi remaining will last a long time in my opinion, if it looks ok now.

Id remove it completely. Usually you can wiggle it back and forth slowly and it will pull right out

Once it's out, what do you do?

Pry out the lead and oakum. Drill in one area to get started.

Ok, but how is that easier than coupling to the galvanized a few inches up the pipe? I used one of these to cut a steel pipe today and it worked great:
