First Claim
1. A toilet comprising:
- a bowl;
a flush valve configured to control flow from the bowl; and
a supply valve configured to control flow to the bowl;
wherein the flush valve and the supply valve are configured such that during a flush sequence the supply valve and the flush valve are both opened and closed twice, first during a pre-rinse cycle and subsequently during a rinse cycle, the supply valve and the flush valve being closed at a start and end of the cycles and open between the start and end of the cycles.

Abstract
A toilet has an electronic flush assembly operable in either a short or long flush sequence selectable by a user. The long flush sequence includes a pre-rinse cycle and a rinse cycle in which the a supply valve and a flush valve are both opened and closed twice, once each first during the pre-rinse cycle and again during a subsequent rinse cycle. The rim supply valve and the flush valve are opened during the pre-rinse and rinse cycles but are closed at the start and end of each cycle. An electronic control controls operation of the valves as well as water supply control components. Level sensors can also be included to provide feedback to the controller, for example, to prevent overflow conditions.
