That "code check" book was written by someone using his opinions, it is NOT a plumbing code. There are "milllions" of flanges installed ON TOP of the flooring. The only ones even with the flooring are those in remodels or when the flange was preinstalled. It is NOT against code to put it on top of the floor, although it might go against the writer of the code check book, but I have never consulted him and do not know what his qualifications, if any, are.
You better buy one and read it hj...the writer quotes codes from both IPC and UPC. I was just really trying to point out yet again an ambiguios item in plumbing. Some say flush with the finished floor, some say on top of the finished floor......I say do what works and doesn't leak.....if you say on top of the finished floor.....I am going with your advice because I can tell from reading your posts you do know what your doing and could fix just about anything that came along....cheers...I'm on my 2nd beer after a day of hard work that incuded some pvc pipe work for venting......
