I'm about to remove a 4" iron soil/vent stack and replace it with plastic.

I intend to "break" the pipe at a vertical socket near to the ground and
replace with plastic above.

What material should I use to seal the joint?

Wind some yarn/heavy garden twine etc round the end of the plastic pipe
to bring its diameter up a little so that it sits comfortably in the
base of the socket, and then fill with mortar, and flaunch off.

Some piccies he
