We were trying to install a new wax ring to our toilet when we realized that the old flange was corroded and so my husband tried to take it off by chiseling it out. He entually got most of it off but there is like a metal ring still attached(it looks like the top of a pipe). I do not know How to attach a new flange? Do I just buy a new one and someone told me I had to drill it in place? We also broke the concrete around the flange and now the floor has all these gauges in it.
HELP!

Take a knife and scrape the ring next to the pipe. Is it shiny and kind of soft? If so that's a lead and oakum joint.
To remove a poured lead and oakum joint take a 3/8" drill bit and drill a few holes down past the lead and into the oakum.. Push a screwdriver under the lead ring and lever it up. Once it's free you can began to peel the lead ring out. Now pick out the oakum and you can pull the joint apart. Good luck, Tom
