I'm going by memory, and that is worth about 1/2 cent.
Yes, after reviewing the Water Witch website (say that five times fast), I believe that you are right. If you look at the picture of the box, the red button is awfully dirty as if it has been pressed repeatedly and often. Not knowing enough about this type of plumbing, can someone answer me this: Might I reasonably assume that the Piezo buzzer is a "full tank" alarm and that the red button activates, (or did at some time in the past), a macerator discharge pump that would then pump the waste overboard, assuming that the valve is configured correctly?
