i have a new european style toilet (made in china) that bolts in the rear. 4" cast iron pipe with no flange. a few questions. i have read that a flange is not absolutely necessary and since my toilet bolts in the rear instead of the sides i hope that is true. i have already installed one of these toilets downstairs and i simply used wood screw closet bolts into wood subfloor and 3" fernco waxless toilet seal which snapped down into my pvc line. easy peasy.
upstairs i have new porcelain tile on top of 1.5-2" concrete. sewer pipe is recessed 3/8" from top of floor (the width of new tile). i was thinking of 4" fernco to provide secure seal. downstairs, this set up also provided some stability as the fernco goes a few inches down into the pipe and locks in. i have read some reviews that the fernco may not work as well with cast iron. more importantly, how do i get screws into the concrete for the rear holes? keep in mind that they have to have threads up. have considered construction adhesive for the toilet which i think would work but obviously becomes a problem if the toilet has to come up for servicing. i cannot return the toilet so i need some creative suggestions. any ideas?
