I am doing my 3rd bathroom renovation in our house and have run into a problem I haven't seen before with the closet flange. I recently tiled the floor and the finished floor is 1.5" above the 90 degree elbow of the waste line. My house was built with 3" ABS waste lines. The elbow is too close to the finished floor. No matter how short the riser pipe is, the elbow causes the closet flange to sit too high off the finished floor. Yet if I try to use a 4" street closet flange, it only covers about 1/2" of the elbow before resting on the finished floor. This doesn't seem good either. My tile is already down but I can access the lines from underneath (will have to remove a little sheet rock but would prefer that over removing floor). Is there a different type of elbow I should be using?
