Abstract:
A swimming pool accessory comprising:a) a planar first wall that abuts a swimming pool side wall adjacent to a water treatment system intake/return when said first planar wall is in position, said planar first wall including (1) a port which is fluidically aligned with the intake/return of the water treatment system when said planar first wall is in position, and (2) a seal on said planar first wall in surrounding relationship with said port, said seal including a linear top rim and a semi-circular side rim, b) a second wall fixed to said planar first wall, said second wall being approximately quarter-spherical in shape and being fixed to said planar first wall along a first peripheral edge of said second wall and extending radially outwardly from said planar first wall along a second peripheral edge of said second wall, said second wall being fluidically interposed between water in the swimming pool and the intake/return of the water treatment system when said second wall is in place; c) a top edge along the second peripheral edge of said second wall, said top edge being co-planar with the top rim of said seal; and d) a fluid flow path being defined between said top edge and said port.
