Toilets, Sinks, Showers, Tubs and Disposals - Really Rusted and Broken Toilet Flange

My toilet was loose so I tried to tighten the nuts on the flange and the entire bolt kept on turning--so I went to the sub-basement to take a look. The closet bent and flange were both rusted, but the flange was severely rusted and broken. I believe that the pipes are 4". I was wondering if there was a way to get that rusted flange off---or is there a way that I could cut the Pipe and maybe using a rubber gasket install 3" PVC pipe and use new closet bend and new Flange. Please help!!
Thanks In Advance

Yes, you can cut the pipe and replace it using PVC and a No-Hub clamp (mission fitting). Sounds like you have cast iron drains.
If the closet bend is not leaking, you could just use a repair flange. These fit over the existing broken flange and screw down to the floor. They have a seal that goes between the old flange and new to prevent leaks. I have included a link for these. Click on the link and scroll down to the 4th set of boxes and it's the one on the left. Good luck.

Thank You!
I hope you were talking about the Super Ring
If I use this---it will not make my toilet too high from the floor will it?
Thanks Again

Yes it is the SuperRing I was directing you to. It will not make your toilet set too high. Wax rings come in 2 thicknesses. You may need the thinner one but I doubt it.
