Lead bend below floor height

[djc621]

I think I have a real problem. In a bathroom remodel the plumbers left a 4" lead bend with about 6 inches above the new floor height. The tiling contractor cut the lead bend even with the floor, (about 1/4 inch above the tile). I cannot take up the entire floor to replace the lead bend. I gather from other questions that I don't have enough lead pipe to make a lip over a brass floor flange. My questions are:

1. How much lead pipe is necessary to be able to turn it back over the brass flange and hammer it down or solder it?

2. If I remove the tile around the pipe I might have enough to make the lip to install the brass floor flange. (my subfloor is 3/4 ply then self leveling compound, then thinset, then tile (altogether about 1 1/4 inches) to get enough lead to bend back over the flange. I could bolt the brass flange to the plywood subfloor.

3. Can I then use second brass flange (not the 1 18 deep) as a spacer to get the flange up to finished floor height?

4. Is it possible to extend the pipe by soldering?

5. If I go with the brass flange, should it be a deep flange? Should it be soldered or should I use plumbers putty?


Thanks very much in advance for any advice you can provide.
