Broken ABS flange on toilet sewer

That's ABS pipe, Best way is to cut it off under the floor and install a new one.
May need a short piece of ABS pipe and a hubless connector to use as a coupling.
You could also cut it off flush with the floor and use one of these.

If it's only the slots/ears that hold the bolts that are cracked or broken, you could use "closet lag screws" (5/16" machine screw on one end, and wood screw on the other end) to secure the toilet directly to the floor/subfloor.

The broken flange remains in place, and the bolts are replaced with the screws I described. Drill pilot holes into the floor/subfloor through the slots (after carefully measuring to make sure they're centered where they belong); screw the closet lags into the pilot holes, and re-install the toilet with a new wax ring. Make sure the screws are either brass or stainless steel.

If the funnel portion (the area surrounding the drain pipe within the inside diameter of the wax ring) of the flange is broken or cracked, then you need to replace it as joecaption described.

Judging by the fact that the OP says the flange is "sealed/glued" to the rest of the toilet pipe, I gather the entire pipe is ABS?

If it has a different type of pipe after the flange, there are other replacement flange options.

Also, one of the flange repair pieces posted above would be worth a shot.

Broken ABS flange

Thanks guys for all the help and suggestions. I will look into using the repair flange that oh'mike suggested and maybe use the "closet lag" as Iasmael recommended. I also thought about possibly filling the are with two part epoxy after making sure of the bolt location. There is a finished ceiling below, so trying to avoid cutting it off and doing the job "right".

Thanks again!
