Abstract:
1. A method for refilling a bowl of a dual flush toilet, comprising: establishing a higher flow rate of water from a refill tube to an overflow tube in a toilet tank for a shorter duration of time in response to a partial flush by aligning a first hole in a slide with a refill tube connector, the first hole defining a first area; or establishing a lower flow rate of water from a refill tube to an overflow tube in a toilet tank for a longer duration of time in response to a full flush by aligning a second hole in a slide with a refill tube connector, the second hole defining a second area smaller than the first area; such that the toilet bowl is filled using the same volume of water from the overflow tube in response to either the partial flush or the full flush, wherein refilling water is delivered from the refill tube into the overflow tube leading into the bowl, and wherein the bowl and the tank refill at the same time such that a shorter amount of time is provided for refilling the bowl after a partial flush and a longer amount of time is provided for refilling the toilet bowl after a full flush.
