  • Patent number: 7150576
    Abstract: A clog free drain for a surface water drain such as that utilized in a tub or stall shower including a basket having side openings permitting waste water to flow there through and into the drain pipe in which the basket is disposed. Directing waste water into the basket is by a sleeve located coaxially of the basket and the drain pipe and below the drain plate whereby the waste water flows through the sleeve, out an opening in the bottom thereof in to the closed bottom of the basket. The waste water accumulates below and into the sleeve and into the basket to a level of the side openings in the basket where it flows into the drain pipe. Pooling of the waste water in the bottom of the basket allows the debris, hair, soap scum and other suspended particles to accumulate in the bottom of the basket and thus separated from the waste water flowing in to the drain pipe.
