    good morning guys,
    we have a customer looking to replace a Gerber 21-310, a floor mount, rear outlet toilet with an American standard yourkville, which is a 4" rough. 1/4" doesnt seem like much, but is it enough to worry about?
    is there enough forgivness in the flange to account for it, or is it going to be trouble?

    You have a 2" outlet on the toilet going into a 3" drain.
    It will work fine.
    Let us know how the new Yorkville works. Pictures would be awesome.

    It's very similar when I'm installing the Gerber rear outlets too.
