Thread: TOTO problem

  1. #1

    Default TOTO problem

    We installed a Toto Dalton toilet the week before Christmas.
    For some reson we can't keep the water level at the acceptable level.
    The water level slowly keeps creeping up and going over the over flow pipe.
    We've tried the adjustment screw and even bent the bar a little to the float.
    Is there a cure for this?

    The most likely thing I can think of is that there is a little bit of dirt/sand/crud on the sealing surface of the shutoff. This can easily happen on new installations if there is something in the supply line/shutoff etc. Usually, if you take the shutoff apart, it can be cleaned off/flushed out, and then it can seal again. Not sure how that one comes apart. One of the pros will have some direction. You can probably find a parts breakdown on the web. Many of the Toto's use a Korky refill valve. Not sure about the one you have.

    This one uses a rod and float ball.

    Sounds like a cleaning of the fill valve is needed.
