Hi folks, I'm installing a new Toto Nexus toilet into a new floor. I haven't installed the toilet flange yet, or the drain piping. I was planning to use a 4" flange and 4" pipe, but I see that there are 4" flanges and reducing 4" to 3" flanges.
I presume that a 4" flange and 4" drain to the stack is better than 3", and that the reducing flange is a potential clog-enhancer. Am I right? Or is there some benefit to a smaller diameter flange and drain?
Thanks!
