Abstract: An emergency shut-off system includes an emergency shut-off switch cover plate with a hinged cover that cooperates with a conventional emergency shut-off switch to help prevent the unintended shut-down of a pool or spa water pumping system. The emergency shut-off switch cover plate and hinged cover function in one mode of operation to prevent the unintended shutdown of the pumping system. In another mode of operation, the emergency shut-off cover plate and hinged cover provide a user with a immediate sensory indication that the pumping system is shut-down and needs to be re-activated. The sensory indication can be either a highly visual indication or in the alternative a combination of the highly visual indication with an audible sensory indication.

Abstract: A skimmer shut-off or plug valve includes an in-line water flow unit that is adapted to be secured in-line to a skimmer suction inlet and an in-line water flow control unit which is adapted to be secured in-line to the water flow unit, which units are rotated relative to one another between a fully open position and a fully closed position to adjustably control the flow of suctioned water through the skimmer suction inlet.
