Swimming pool drain

Abstract

A polymer plastic drain apparatus for the aggregate decking areas of a swimming pool. The drain is comprised of an elongated trough adapted for burial in the aggregate and is formed of a bottom wall and parallel spaced apart upright sidewalls terminating at their upper distal ends in a bifurcated formation defining an intervening space of selected cross-section. Adapted to overlie the trough in a removable mounting relation thereto is an apertured grating having elongated skirts downwardly depending from the longitudinal edges thereof. The skirts are insertable within the intervening spacing of the bifurcated trough formation in a springlike interfit enabling the grating to be removed and replaced as appropriate. Internally of the trough are a plurality of longitudinally spaced transversely arranged sleeves extending between openings in the opposite sidewalls. The sleeves enable reinforcing rods to be implaced and embedded in the decking aggregate when poured and serve to anchor the trough in place within the aggregate when set while inhibiting expansion and contraction of the decking in the areas surrounding the drain.
