  • Patent number: 7820041
    Abstract: A uniquely designed drain cover for swimming pools, spas, whirlpools and the like that is non-flat and clover shaped containing three or more “leaves” that provides for strengthened rigidity, increased protection against hair and body entrapment and that is connected to the sump through ribs that run across the body of the drain cover that allow for securing the drain cover to the sump through these ribs in addition to the perimeter providing for greater anti-deflection properties and anti-vortexing properties. Apertures found on the surface of the cover and along the perimeter add to the anti-deflection and anti-vortexing properties of the cover.

  • Publication number: 20100140192
    Abstract: A uniquely designed dual port spa suction fitting that uses two channels for the intake of water to be filtered that are bridged together to eliminate high speed zones and provide for a more even distribution of suction force across the suction openings. The cover has a concave shape with a curved perimeter and sidewall. The cover, the curved perimeter and the sidewall all contain a plurality of apertures allowing for the intake of water into the filter. The apertures provide for unidirectional flow, thereby reducing the hazard caused by hair entanglement. An alternate embodiment includes a sump that is attached between the cover and the two spa fittings.
