  • This quantity is at least the quantity required for sealing bend (trap) 56.
  • This quantity is less than the quantity of water used for "full” flushing or "half flushing of a common toilet bowl (i.e., flushing after urinating in common flush toilets). The lesser quantity is adequate since the bend (trap) of the toilet bowl is emptied before flushing, and therefore the flushing only washes up the bowl, and seals the bend (trap).
  • An additional advantage of the present invention is the fact that the user does not have to touch the flushing handle, as in a common flush toilet. Since foot pedal 24 is used only as a sensor for indicating that the user has activated the flushing process, the pedal can be replaced by a switch attached to the floor. The mechanism of a switch is much simpler and more reliable than the mechanism of the pedal.
