    in 1998 my plumber on my new house used a 1/4 bend at the bottom of my toilet drop(approx 24 inch drop)before it turns horizontal. I am redoing the bathroom and rough in could be simpler if I reused this transition but in NH under IPC it appears to me this should have been a long sweep elbow. This is a 3 inch ABS pipe. Could the requirements have been different under IPC in 1998 or did my plumber not do it right to begin with?

    I thought closet bends were always an exception to those requirements.
    I found these references to water closets in the current IPC but not a direct mention of it's exception.
    The current chart for change of direction fittings, does appear to allow a short sweep for 3" and above.

    I'm sure the plumbers will confirm it one way or another.

    thanks for the reply but I have no reduction in size nor a 4 x 3 flange. I'm simply talking about a change in direction from vertical to horizontal and that my plumber used a regular 1/4 bend fitting

    I was thinking more along the lines of the radius of a closet bend being acceptable, which I don't believe has a larger radius.

    Also, would a short sweep work?

    Well according to IPC table 706.3 a short sweep would have worked but I don't believe any such fitting exists in ABS?
    I was mainly curious why my plumber had used a 1/4 bend when under IPC it looks unacceptable. Didn't know if that was allowed in 1998?
    I am moving toilet and can basically fit anything I want to.
    So I will probably go with a wye and a 45 as I have to have another fixture drain into it as well.
    Thanks for your help
