    Hi All,

    Just did a remodel and realized the drain pipe to the wall (unchanged) is
    too high.

    The remodel has double sink with disposal. Since the pipe to the wall is
    so high, it creates a static water level that backflows into the disposal.
    See attached photo (sorry about the blur, thanks I-phone). Add in the
    T for the connection of the 2 and it makes it a bit lower.

    From sketch point of view -

    Sink
    | | +---------
    | | | +------
    Disposal-------+ | | |
    Pipe ------+ | | | P-Trap
    | +--+ |
    +-------+

    As you can see, the static water level will be above the dosposal pipe.
    Any ideas on how to solve this problem?

    Thanks!

    I think you will have to open the wall and lower the drain. Maybe some pros will have a better solution, but it sure seems to me you will be trying to make water run uphill and that's difficult to do.
