Abstract
An elongated suction outlet assembly is provided for use in swimming pools, hot tubs and the like. The suction outlet assembly includes an elongated sump having at least one longitudinal, raised island extending upwardly from inside the sump, and an elongated cover engaging the sump. Safety features of the suction outlet assembly are designed to inhibit human entrapment and thereby reduce the related risk of serious injury or death. The cover is long enough to prevent a bather's body from covering and blocking all of the openings therein, and thereby avoids the creation of a dangerous entrapping force. In the event the cover becomes separated from the sump, the raised island(s) provides a back-up safety feature by preventing a bather's access to the suction outlet nozzle via narrow axial flow channels, thereby virtually eliminating the risk of limb entrapment.
