Normally you would use a 2" donut or pour lead for a joint like that.
I use one like in the picture, but a 2"
You can't use plumbers putty.
I could use some advise on what to do about this connection I have found under my new (used) house. It looks like someone connected the KS drain to the cast iron using plumber's putty to seal the connection.
Can I have a plumber use oakum and lead wool to fix this and still pass code in California? I was thinking of using the connection as a cleanout instead, the connection is right at the foundation and would seem to be a very good place to have a cleanout (there are no cleanouts in the house, as of yet.)
Thanks in advance
I had not heard of a donut before. Looked it up on the Internet after your post and found previous posts on your forum about donuts, cannot find a marking for what type pipe it is (sv vs x?) will try sv first. Thanks for your help.
Be sure to clean the inside of the hub first, because that surface is also a sealing point. I would take the ABS out, pour a lead joint to secure a short piece of cast iron into the hub, and then use the proper transition coupling to connect to the ABS. In the process I would install a cleanout tee.
