How to Remove this Rusty Toilet Flange

[McHowsh]

Hello Friends! I need good advice for proper method of removing this flange. The cast iron flange seems to rotate freely around the pvc insert, but the insert itself is glued to the waste pipe. How can I get that off without damaging the pvc waste pipe?

I was going to try the repair flange thingies that you just slide underneath the existing flange, but I can't slide them under given tight fit with the tile. Besides, this flange is so rusty I'd rather install a new one.

Thanks in advance for any help!

The ring spins so you can glue the fitting in first then rotate the cast iron flange where it belongs and secure it to the subfloor.
It doesn't look that bad.
Removing it requires a special auger/drill bit.

Do you want to remove the whole flange or the metal ring?
You can remove the metal ring and replace it with a new stainless steel one.

I don't see anything much to be concerned about, but if I were going to remove it I would be interested in the accessibility from below.

Cacher Chick is of course correct. Just drop two wax rings on there and install your new toilet. If you want to position the ring to a fixed position, shoot a screw into one of the screw holes. Just remember to aim it properly. I have seen more than one where the wrong part of the slot is positioned at 9 o'clock and 3 o'clock.

I would be very concerned about the left slot having rusted COMPLETELY away so the bolt will either be loose NOW, or soon afterwards.

Hi Flapper, appreciate the question! If I can replace the ring and leave the flange, I'll do that. What is best way to remove the ring? And will I have issues inserting a new ring given limited space between existing ring and tile?

thanks for the reply! I guess I'm one of those DIY'ers that always goes above and beyond...never taking shortcuts or hoping things will be good. If I see something nearly rusted out I like to replace it. Must be my OCD. ;-)

Cut the ring off and slip a repair ring into it's place so that you will have 2 good t-slots for the new bolts.

If the subfloor is good, you could install an anchor bolt into the floor instead of replacing the ring.

You are saying a flat repair ring was too high. https://terrylove.com/forums/index.php?threads/broken-closet-flange.56422/#post-415004
