I broke my PVC toilet flange when I over-tightened the bolt used to secure the toilet to the flange. How do I fix this without replacing the entire PVC fitting? This PVC flange is glued to the drain pipe so I can't just pull out the fitting to replace it.
Here is what it looks like, the red circle shows where the bolt was that snapped the flange.
Check out some of the fittings and repair parts from Oatey. Not sure what sizes of pipe you have. But if you have a 4 inch pipe, 43539 is supposed to slide inside of it. It has a rubber piece that expands using 3 socket cap screws.

I have been repairing my own toilet bend, which is a lead piece coming from a cast iron drain stack. I would have used that part above, but I think I'm going to go with a 3x4 repair flange instead because this non expanding flange was shorter and fit better. The "3x4" part means it will fit over a 3" pipe or fit inside a 4" pipe.
I hope this helps, every toilet flange problem is different. I had to buy many of the repair parts and test fit them before I found the right piece.
Yep, you've got to cut it and should then use a Fernco coupling to plumb a modern PVC flange into the system. In the past I've tried unscrewing cast iron but it always breaks, sometimes shattering past a convenient cut point!

You can purchase a toilet flange repair at any big box hardware store.
Remove the wax ring (buy a new one), remove the bolts, and mount this on top of the existing broken flange:
Then reattach the toilet as per normal, making sure not to over tighten.
Tip, seat the toilet firmly on the wax ring before you tighten the bolts, and use a STANDARD sized wax ring not a jumbo - if the toilet starts out firmly on the floor before you start tightening then you know you're tight enough when the washer starts to bend in just a little.
