Abstract: A water diverter assembly is positionable in a skimmer chamber between a well and a pool. A bar has opposed ends removably received in and supported by the chamber. First and a second similarly configured plates have interior ends with first radii of curvature adjacent to the well and exterior ends with second radii of curvature greater than the first radii of curvature adjacent to the pool. Regions join the bar and the plates. The plates are closest together at the interface of the interior and exterior ends. The plates increase their separation at the interface during operation and use in response to the flow of water between the plates.
