I know this isn't to code, but is this toilet going to have problems such that something should be changed before drywall is put back up? (This was installed in this fashion by a licensed plumber due to space limitations.) The line that runs into the sanitary tee before going to the drain is from two sinks. Given the reducer attached to the sanitary tee and the use of the sanitary tee on its side, will waste have a tendency to collect there?
