I ran into something with a toilet flange I really need help with. The wax seal apparently had breached so I pulled the toilet. The flange is recessed and isn't cleaning up too well. Appears to have concrete on it which I can only guess may be from the quickset concrete used on the tile. Not knowing for sure if what I'm looking at is a pipe flange permanently welded on the end of a pipe OR a leaded on flange, I'm nervous about chiseling the concrete away and am thinking about other options. I have a flange extension (see pic) that I'd thought about trying to use. One side has a black neoprene gasket on it and I'm assuming that's face down on the original flange with a wax ring and then the toilet. The other option is trying to just use a thick, reinforced was ring w/flange and hope for the best. Any suggestions are appreciated. TIA
