ABSTRACT:
A divider plate having a strainer basket depending therefrom is positioned in a skimmer apparatus intermediate the skimming inlet and the lower end. A conduit passes through the basket and communicates with the drain inlet in the bottom of the skimmer which also includes an outlet from which water is drawn by the swimming pool pump. The conduit is aligned with a water passage in the divider plate. A coupling member affixed to the hose associated with vacuum cleaning equipment is passed through the water passage and engaged with the conduit. The coupling blocks water flow from the drain inlet and has an exit therethrough for movement of water from the hose to the outlet of the skimmer. Valve means are provided for selectively closing the water passage and for selectively retarding water flow from the drain inlet.
