I replaced the toilet flange in my Monty. It was black ABS and was screwed down. Very easy job. As far as the down pipe goes, one of the glued joints in mine later developed a leak. Not wanting to replace the flange again, I cut the down pipe and removed the upper section which was screwed to the bottom of the flange. Then I pieced together a new upper section of the down pipe and cut it off just short of coming in contact with the down pipe that went to the black tank. I then used a 4" flexible coupling to connect the two pipes. Been working fine for several years.
