I had a leaky toilet and had to replace the subflooring in the bathroom. The flange is also rusty and a little warped and must be replaced. I've seen plenty of videos telling me to score the flange fitting and use a screwdriver or chisel to break the glue and remove the fitting from the pipe. However it looks like primer was used in my case and I can't get the fitting to budge. I'm afraid of breaking the pipe and ending up with a real mess.
What is the best way to remove the flange if it was installed using primer and glue?
