A circular suction outlet assembly is provided for use in swimming pools, spas, and the like, which includes a sump body having a central stem which forms an annular space within the sump body, and a nozzle which communicates with the annular space to convey water to the swimming pool drain circuit. A circular, domed-shaped cover is removeably fitted to the top of the sump body. Safety features of the suction outlet assembly include openings in the cover arranged to allow a bather to safely break a seal formed between a body part and the cover. In the event the cover becomes separated from the sump body, the annular space and the central stem also inhibit the insertion and entrapment of human body parts in the sump body.

An underwater light, e.g., for a pool or spa, includes an ordinarily watertight housing, an outer compartment within the housing and floodable by water flowing therein in the event the housing is no longer watertight, a current shield within the outer compartment and at least partially defining an inner compartment within the outer compartment, a light emitter within the inner compartment, a passageway communicating between the inner and outer compartments such that outer compartment flood water can enter the inner compartment and contact the light emitter, and a conductor. The conductor is positioned so as to collect stray electrical current conducted from the inner compartment by water within the passageway, thereby reducing the risk of shock presented by such stray electrical current. The underwater light is installable within a wet niche, and includes a transformer housed in a separate compartment that extends into the wet niche for thorough cooling thereof.

A pump for use with a fluid circulation system for a recreational water body is disclosed. The pump includes a strainer housing, an impeller housing integrally formed with respect to the strainer housing, and an impeller cover mounted with respect to the impeller housing. The strainer housing includes a top portion having an outer surface adapted to engage with a strainer housing cover for mounting the strainer housing cover with respect to the strainer housing. A plurality of cams are formed circumferentially with respect to the outer surface of the top portion of the strainer housing. The cams are configured and dimensioned to cooperate with corresponding cam members formed with respect to an inner surface of the strainer housing cover. A positioning tab is formed with respect to the top portion of the strainer housing for appropriate alignment of the strainer housing cover. A positioning notch is formed with respect to the inner surface of the strainer housing cover. The notch cooperates with the tab to ensure proper strainer housing cover alignment. A stand is provided that defines a receiving chamber for receiving a securing feature that is mounted with respect to downwardly extending base portions associated with an impeller housing and an impeller cover.

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.

A fluid distribution system for controlling the operation of a swimming pool cleaning device includes a housing having an inlet for receiving a supply of pressurized fluid, a plurality of outlet openings and a valve chamber between the inlet and outlet openings. The housing has at least one compound cylinder having two portions with different bore diameters for slideably accommodating therein a mating stepped piston. Each portion of the compound cylinder fluidly communicates with pressurized water in the valve chamber via associated fluid pathways. The larger cylinder is vented by a relief valve actuated by a fluid driven cam that periodically opens and closes the relief valve. When the relief valve is closed, the pressure within the large cylinder pushes the piston to a first position which effects the opened/closed status of a port, e.g., allowing one of the outlets to communicate with the pressurized water in the valve chamber. When the relief valve is opened, the pressure within the larger cylinder is reduced, allowing the pressure in the smaller cylinder to push the piston to a second position which effects the opened/closed status of the port and/or opens another port to allow the pressurized fluid to be discharged through another outlet.
