  • Anti-vortex drain
    Patent number: 5341523
    Abstract: An anti-vortex, flush-mounted floor drain for swimming pools consists of a main housing, which is in the form of a hollow cylinder of a first predetermined diameter A drain opening is located in the top of the hollow cylinder; and the edges of the top of the cylinder are mounted flush with the floor of the swimming pool. A downwardly sloped lip extends from the top edge of the main housing and terminates in a circular opening in the top of the main housing. A solid circular cover is centrally mounted in this opening in the main housing, and is movable toward and away from the opening in the main housing to vary the size of the water inlet from the pool between the edge of the circular cover and the edge of the opening in the main housing. A drain pipe is connected to the main housing for withdrawing water from the housing. The large circular cover at the center of the drain prevents a vortex from occuring as a result of the suction of water passing outwardly through the drain pipe in the drain housing.
