[ What is claimed is:] [1.]1. An apparatus for straining fluid flow in a drainpipe, the apparatus comprising:a drain plate for covering an entrance to a drain pipe, the drain plate providing a plurality of drain plate openings for admittance of a draining fluid into the drain pipe;a cylindrical body having a sidewall terminating with an integral closed end engaging the drain plate, and extending downwardly from the drain plate to establish an open end of the sidewall and an integral uniform peripheral flange extending outwardly from the sidewall, for tight fitting with the drain pipe inside surface, the side wall providing a plurality of apertures therethrough and a further plurality of surface protuberances extending outwardly from an exterior surface of the side wall, the cylindrical body positioned for receiving the draining fluid from the drainpipe, radially inwardly into the cylindrical body through the apertures.
