Water removal device

Abstract

A water removal device to withdraw virtually all the water from the drain in the bottom of a swimming pool comprising an elongated lower suction or vacuum housing including a plurality of perforations or holes formed therein to receive water from a pool drain and an upper suction or vacuum source to create a suction or vacuum to draw water from the pool drain through the perforations or holes into and through the lower suction or vacuum housing to remove the water from the pool drain.

1 . A water removal device to withdraw virtually all the water from the drain in the bottom of a swimming pool comprising an elongated lower suction or vacuum housing including a plurality of perforations or holes formed therein to receive water from a pool drain and an upper suction or vacuum source to create a suction or vacuum to draw water from the pool drain through said perforations or holes into and through said lower suction or vacuum housing to remove the water from the pool drain. 
     
     
         2 . The water removal device of  claim 1  wherein said elongated suction or vacuum housing comprises an elongated lower suction or vacuum chamber cooperatively formed by an elongated arcuate or convex bottom wall having a plurality of intake perforations or holes formed therethrough, a side wall extending upwardly from each side of said elongated arcuate or convex bottom wall, an end wall extending between corresponding ends of said side walls and a top wall having an outlet port formed therethrough extending over the upper portions of said side walls and said end walls. 
     
     
         3 . The water removal device of  claim 2  wherein each said end wall includes a plurality of intake perforations or holes. 
     
     
         4 . The water removal device of  claim 2  wherein said upper suction or vacuum source is detachable coupled to said elongated lower suction or vacuum housing by an intermediate hollow coupling sleeve. 
     
     
         5 . The water removal device of  claim 4  wherein each said end wall includes a plurality of intake perforations or holes. 
     
     
         6 . The water removal device of  claim 4  wherein a flow aperture is formed in the lower wall of said intermediate hollow coupling sleeve disposed in alignment with said outlet port formed in said top wall of said elongated lower section or vacuum housing to drain water from said trough through said intake perforations or holes through said outlet port and said flow port to said intermediate hollow substantially cylindrical coupling sleeve. 
     
     
         7 . The water removal device of  claim 6  wherein a sealing ring or flange is disposed between the lower portion of said upper suction or vacuum and said intermediate hollow coupling sleeve to form a seal therebetween to maintain the suction or vacuum between the trough of the drain and said upper suction or vacuum source. 
     
     
         8 . The water removal device of  claim 2  wherein said elongated lower suction or vacuum housing and the upper suction or vacuum source comprise a single unitized device or unit. 
     
     
         9 . The water removal device of  claim 2  wherein the outside diameter of the lower vacuum housing is greater than the distance between said upper ends of the side walls such that said intermediate coupling sleeve rests on said lips or support shelves to hold said water removal device in spaced relationship relative to the bottom of the pool drain. 
     
     
         10 . The water removal device of  claim 4  wherein the outside diameter of the lower vacuum housing is greater than the distance between said upper ends of the side walls such that said intermediate coupling sleeve rests on said lips or support shelves to hold said water removal device in spaced relationship relative to the bottom of the pool drain.
