Abstract

The invention relates to a cover and sump assembly for a main drain of a pool or spa that prevents suction entrapment, and specifically, to an assembly having a frame with openings, plates with openings positioned on the frame, and a sump for collecting water and receiving the frame. The assembly reduces the velocity of water flowing there through, uniformly distributes a suction force created by water flowing into the sump, prevents a vortex of flowing water above the assembly, and provides anti-entanglement features to minimize the likelihood of an individual becoming entrapped on the assembly by a suction force produced by a pump in the pool or spa filtering system. The assembly includes a conduit defining an opening along a lower portion thereof that reduces the velocity of flowing water at the suction opening in the sump by reorienting the suction port from a vertical to a horizontal orientation.

Description

CROSS-REFERENCE TO PRIORITY APPLICATIONS[0001]This application claims the benefit of and priority to commonly owned U.S. Provisional Patent Application Ser. No. 61 / 091,998, filed Aug. 26, 2008, in the U.S. Patent and Trademark Office. This application incorporates the provisional application by reference in its entirety.BACKGROUND OF THE INVENTION[0002]The invention relates to a cover and sump assembly for a main drain of a swimming pool or spa that prevents suction entrapment, and more specifically, to a cover and sump assembly having a frame defining a plurality of openings, one or more plates defining a plurality of openings and positioned on the frame, and a sump for collecting water and for receiving the frame. As configured, the cover and sump assembly reduces the velocity of water flowing through the assembly, uniformly distributes a suction force created by the water flow in said sump, and prevents a vortex of flowing water above the assembly, provides anti-entanglement feat...
