Getting ready to do a levelling/flattening pour on bathroom floor but need to decide what to do with the flange first as it is was put in too low originally. The floor around the flange shouldn't be raised up by the pour, as it the high spot, but if I should fix the flange I want to do it prior to leveling.
Obviously this can (and has) worked with 1/2"-3/4" flooring, via things like flange extenders and Fernco wax-free seal, but it is not obviously not desirable or correct to have not be flush with the finished floor (or on top of it). It appears to be the external fit to the 3" pipe which seems to make removal difficult from what I've been able to look up. Extra difficult given it is embedded in concrete and risky if I were to damage the pipe it is connected to.
Looking for suggestions as to whether to leave it as is or not, and if not, how best to approach the difficulty of removing it to add a new one (that can go up an inch).
