Abstract
An improved leaf removal system is disclosed for removing leaves and the like through the floor drain of a swimming pool. conventional recirculation system for the pool. This is accomplished by providing a leaf removal chamber adjacent the pool, with a water outlet from the bottom of the chamber to the pool. The floor drain is interconnected by means of a pipe to a water inlet near the upper end of the chamber, and this inlet is located beneath the water level of the pool. A strainer basket is removably placed between the water inlet and the water outlet in the chamber. Return water for the pool is supplied to an entrainment nozzle connected to the water outlet in the chamber to cause a venturi effect to draw water, along with leaves and other debris, from the floor drain into the water inlet of the chamber, from which such water is returned to the pool, along with return water supplied to the entrainment nozzle. In this manner, the leaves and other debris are removed from the pool without passing them into or through the pool recirculation system.
