ABSTRACT:
A control device for regulating the skimming flow of surface water from a swimming pool to a perimeter gutter includes a housing disposed in a gutter wall, at the normal level of water in the pool, which defines a flow passage from the pool to a lower gutter trough. A plate pivotally supported within a downwardly-sloped portion of the flow passage reduces flow through the housing in response to increasing levels of water in the trough. The plate closes the flow passage when the water in the trough exceeds a predetermined level to prevent flooding of the gutter and to prevent back flow of water from the gutter to the pool.
