    May I first ask: why are you trying to remove the flange ?

    Because the slot where one of the bolts slide into ion the flange is broken... its a plastic flange.

    If it is just the slot that is broken, you can buy a repair part to replace the broken part of the flange. This piece is a metal arc that is about 3 1/2 or 4 inches long with a hole for the bolt. You put your bolt in place and slip the piece under the broken flange. This will only work if not too much of the flange is broken.
    Let me know if you don't think this will work, maybe I can tell you something else.

    It is quite difficult to remove glued toilet flange.

    You can proceed as Letmetellu suggested. Also, you may consider drilling directly into the concrete, epoxying new bolts in pre-drilled holes and set toilet onto these bolts.

    You can also purchase new, retrofit, ABS toilet flange that fits inside existing pipe. In this case, you can cut off existing flange, insert the new one, bolt it into the sub floor / slab and install toilet on top of it.

    Hi All...

    Siedoman...

    If you go to your local plumbing supply house on Monday you will find that they sell a BIVALVE type of replacement ring for pvc flanges... click on the attachment below to see what I mean.

    The name of the particular kind of bivalve ring in my pic. Is called a CLAM repair ring. Here, just need to unscrew old flange and then cut it off using aviation/tin snips and then simply place the bivalve ring into same slot as old ring, clamp around and then screw/anchor into floor.

    I have also included a picture of one type of spanner flange kind of like Letmetellu talked about. This will work fine if most of the ring is still intact, but nothing beats the clam bivalve repair ring as bad flanges that are broken on left are usually also weak on right, etc.

    Let us know how you make out...
