Abstract
Various systems and methods of controlling the flow of water from a fill valve in a toilet tank to a toilet bowl of a toilet using a bowl fill valve are provided. An inlet of the bowl fill valve is coupled to a bowl fill outlet of the fill valve and the outlet of the bowl fill valve is channeled to the toilet bowl. In illustrative embodiment, a method is provided comprising the steps of determining when the toilet tank has been substantially drained of water during a flush cycle, and opening the bowl fill valve for a predefined period of time after the toilet tank has been substantially drained of water to fill the toilet bowl of the toilet with water. The predefined period of time is less than a total time of the flush cycle.
