wye fitting with back to back toilets

[truthseekerz]

Hi. I just bought a Toto ultramax and would like to put in another that backs up to this one. The installation instructions say the the G-Max and Power Gravity flushing stystems are not specified for back-to-back installations. The only means is when the toilet drain connections incorporate a WYE fitting. How would I know if I already have this and if not, how is it installed? Does the floor need to be torn up or what? Thanks!

The only way to find out what kind of fitting you have, without taring out the walls and/or floor, is a drain video camera
