ABSTRACT:
A flush valve water accelerator having a top opening of increased height to reduce the amount of water used by a toilet, and which accelerates the flow of water to increase the efficacy of the water in the toilet bowl. The device is comprised of an entry tube and an exit tube, with the exit tube having a minimum inside diameter of approximately fifty (50) percent of the median inside diameter of the entry tube to accelerate the flow of water into the toilet bowl without causing cavitation from the vacuum created by the restriction of the exit tube. A connecting tube, having a decreasing inside diameter, connects the entry tube and the exit tube.
