Abstract
A swimming pool leaf trap and main drain assembly collects and removes leaves and other debris from the floor of a swimming pool. The assembly includes a main drain recessed in a swimming pool floor and formed with a drain opening connected to a return line. The main drain removably houses an apertured basket that receives leaves, the normal downward flow of swimming pool water through the main drain trapping the leaves within the basket. The cover of the basket is provided with a lifting ring which is engaged by a brush handle to raise the basket to the surface. During such upward movement, the downward force of water through the basket holds the leaves within the basket. An anti-vortex plate covers the main drain opening when the basket is removed from the main drain. The cover of the basket is released from the basket at the surface to permit removal of the leaves trapped within the basket.
