I bought a new toilet for basement bathroom... now I find the plastic flange in floor is broken. I have read about repairing it, but am not sure of the best way to attach the new partial flange to the old one. The floor is concrete and it looks like the old flange was set into the concrete when original toilet was installed. I assume that I need to screw the new partial flange through the old one, into the floor.. but what should I use? I have read about tapcom screws for concrete... are these my answer and what size would I use?

(I suppose trying some kind of industrial glue to attach the two flanges would not be good? )

All tips and advice is appreciated.

We use 1 1/4" Tapcoins to secure the flange. This requires a Tapcon kit. You can also use 1/4" plastic inserts and wood screws. This requires a 1/4" masonry bit. Forget the glue.
Good luck, Tom

Is your old flange a PVC flange with a metal ring around it. If so and it is the metal part that is bad, that can be replaced with a part called a "Bay Flange". It replaces the metal part and nothing else has to be done.
