  • Patent number: 7376983
    Abstract: A debris catch assembly used between a plumbing fixture and drain piping. It has two strainers and structure for supporting the larger strainer in a superior position. Both strainers are configured with holes through their side and bottom surfaces, to catch all types of solid debris in waste fluid, including hair. During use, both strainers are rapidly removed and inserted without tools into their usable positions from a location above the plumbing fixture's drain opening. The larger strainer initially catches all of the debris. When it is filled up, it is withdrawn from the drain via finger engagement with a protruding stub, after which collected debris is emptied into a dry waste receptacle. During such cleaning, debris collects in the second strainer. When void of fluid, the second strainer can be removed from the drain for cleaning via a handle having a bent configuration that clears the strainer above it.
