Abstract
A pool drain assembly for a swimming pool having a vinyl liner is disclosed. The assembly includes a drainage receptacle which has an upper edge portion substantially at a level defining the bottom of the swimming pool. The receptacle has a conically shaped seating surface, and the vinyl liner covers the surface. A clamping ring is seated on the seating surface and surrounds a strainer plate which also rests on a lower edge of the seating surface. The upper surfaces of the pool liner, the clamping ring, and the strainer plate are all substantially co-planer.
