copy and paste from OP. did you see this?:::::

The top of the cast iron above the connection is already
supported so it can't drop down when I take out the bad section

What I am thinking of doing is breaking out the bad/cracked section of
cast iron, and hopefully ending up with a clean male end of the cast
iron at the top



be sure to support the cast iron above before removing the section to
be replace.

or the entire line may move, causing a rroof leak, cast iron is very
heavy
