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.

Strainer housing assembly and stand for pump

Disclosed herein is a liquid pump for use with a fluid circulation system for a recreational water body. The liquid pump includes a strainer housing, a pump housing assembly secured to the strainer housing, and a lock ring fastened to the pump housing assembly. The pump housing assembly includes an outlet that is rotatable between a first position and a second position and further includes an annular protuberance defining an inlet. The strainer housing includes an outlet, and the annular protuberance extends through the outlet of the strainer housing into a chamber thereof. A clip is positioned within the chamber and releasably secures the annular protuberance so as to inhibit inadvertent disengagement of the strainer housing from the pump housing assembly.

An underdrain assembly contained within a swimming pool filter has a plurality of laterals, each of which is pivotable between a non-operating position and an operating position. Each of the laterals is threadedly attached to the underdrain assembly so that they can be replaced individually by unscrewing them from the underdrain assembly without removing the underdrain assembly from the filter. The laterals can be locked in their operating positions by either a reversible locking mechanism or an irreversible locking mechanism. With the laterals in their non-operating positions, the underdrain assembly and the laterals can be inserted into the filter as a unit.

A skimmer for skimming water from a swimming pool or spa is provided with entraining means for entraining additional water from the pool or spa to thereby increase the flow of water into and out of the skimmer. The entraining means includes two nozzle members which cooperate with each other to jet an entraining stream of water through the skimmer. The skimmer is also provided with isolating means for isolating the entraining stream of water from the rest of the water flowing through the skimmer. The isolating means includes actuating means for selectively actuating and deactuating the isolating means such that the skimmer can be operated at a normal flow rate when the isolating means is actuated and at an increased flow rate when the isolating means is deactuated.
