Abstract:
1. A drain assembly for installation in a wall of a pool comprising: a. a drain body having an annular mouth defining an inner and an outer boundary serving as a fluid flow inlet, a spaced apart fluid flow outlet positionable below the mouth and a side wall interconnecting the mouth with the outlet and defining a fluid flow chamber, the cross sectional area of the fluid flow chamber decreasing from the mouth to the outlet; b. a fluid deflecting plug having a comparatively large area top and defining the inner boundary of the mouth, a comparatively small area base and a side wall interconnecting the top and the base to form the plug with a cross sectional area decreasing from the top to the base; c. a support structure for positioning the plug within the drain body such that at least a substantial portion of the sidewall of the plug is spaced apart from the sidewall of the drain body to define a fluid flow channel having a first comparatively larger cross sectional area in proximity to the mouth and a second comparatively smaller cross sectional area in proximity to the outlet to provide a lower fluid flow velocity at the mouth than at the outlet when fluid is transferred from the pool through the drain assembly; and d. a pump for drawing water through said drain body.
