: With a 1.6 gpf toilet, I would like to use an : off-set 3 closet flange to avoid notching : a floor joist (tight spacing with no option : on toilet location). Visually judging, it : would appear that a 2 dia. ball would clear : the off-set. With a 1.6 gpf toilet, could : there conceivable be a flushing problem? : Toilet uses elongated siphon action jetted : bowl.study this situtation real careful, if at all possible use a regular flange. the very design of most off set flanges make it hard to get a good seal. dont use a horn seal as this will futher block passage. consider adding reinforcement to other side of joist.
