I am retiling my bathroom floor and need to replace the subfloor to accomodate the new tile.
I removed the toilet and want to start replacing the plywood subfloor, however I'm not sure how to remove the toilet flange so that I can lay the new plywood properly and get a nice tight fit around the drain pipe. The drain pipe appears to be 3" copper Type L (the flange also looks to be copper). If this is similar to working with smaller copper supply pipe (which I have experience with), I was thinking I could heat up the "bend" fitting below the subfloor and just pull out the flange once the solder melts. Then I could "resweat" the joint when I'm done. However, I've never worked with pipe this thick and didn't know if I was biting off more than I could chew. Does this sound like a good plan?
