In my master bath remodel, I'm planning on removing the old toilet flange and replacing it with a newer one. The house was built in the early 80s and looks like a metal flange glued to the ABS drain pipe. The flange sits inside the ABS pipe.
What is the best way to remove the old flange? I have access to the ABS drain from inside the floor. Is it easiest to just cut the ABS pipe below where the flange insert ends? Then add a coupling and new ABS pipe to reset the height for the new flange?
Thanks in advance for any comments.
