A drain for swimming pools, spas, whirlpool baths, etc., includes a plurality of first orifices in communication with corresponding serpentine passageways to minimize hair or a body part from covering and entering the first orifices to a degree sufficient to entrap a bather. A plurality of second orifices independent of the first orifices and in fluid communication with one another through a peripheral passageway provide a flow of water from the peripheral passageway into the serpentine passageways to create an alternate water inflow path and reduce the pressure differential and possible entrapment that might occur should a body part or hair come in contact with or enter the first orifices. Moreover, a plurality of ridges are attendant the first orifices to reduce the likelihood of direct contact with the first orifices by a body part or hair.
