How do I replace a cast iron flange?
How do I replace a cast iron flange? It is welded on I think. I removed the screws and it of course didnt come off. I have a new PVC one, but not sure how to get this flange off. The bolts are corroded and old and just keep spinning, so I need to replace it.

It sounds like you just want to replace the bolts. They are not connected to the flange if they are just spinning and the toilet is still installed then grab them with a pair of vice grips and cut the nuts off. The new bolts slip into a space on the flange the same was as they do with the pvc flange.The cast iron flange is attached with lead and very difficult to remove. Once you got it off you wouldn't be able to simply attach a new pvc one, it would involve a lot more work.

If you have to replace this is how; put a rag down the pipe so you don't drop something down the waste line, take a drill and drill a series of holes in the lead thats between the pipe and the flange, take a screwdriver or small chisel and pry the lead out; if this dosen't work, drill more holes.
A standard PVC flange will not work on a cast pipehttp://www.plumbingsupply.com/images...ue-c40-500.jpg This link will show you one that will work
