Abstract: A multi-weir door assembly is coupled to a skimmer body near a front entrance of the skimmer body such that a flow of water received in the front entrance is incident on a front side of the multi-weir door assembly. The multi-weir door assembly comprises multiple weir doors that are rotationally coupled to the skimmer body by at least a first hinge assembly. Each of the weir doors has a respective buoyancy, and at least first and second weir doors of the multiple weir doors have first and second buoyancies that are different from one another such that the flow of water incident on the multi-weir door assembly affects the first and second weir doors differently in terms of an angular degree to which the incident flow of water causes the first and second weir doors to rotate about first and second axes of rotation, respectively.

Abstract: A low profile spa jet having a structure allowing for the use of a jet housing for both threaded/nut and grommet installation, wherein the jet protrudes into the spa tub less than 0.5?. The low profile spa jet also can have a jet face/flange that is interchangeable between threaded and grommet jet bodies without changing the relationship to the spa wall, wherein the jet protrudes the same amount in the installed state for both styles of jet body. The low profile spa jet also can have a jet face/flange that is removable and/or interchangeable before and after the jet body and jet internal are installed in the spa.

Abstract: A light system having a lens component with at least a portion of the lens configured for receiving an aesthetic material allowing the light system to match, blend in with, or compliment a pool or spa wall or floor, while allowing at least a portion of the light to be emitted into the pool or spa interior, and a housing component for attaching to a pool or spa wall or niche or passage in a pool or spa wall.

Abstract: A pool drain or sump basin having elongated ring-shaped body, at least one and preferably a plurality of outlet ports about the ring-shaped body for allowing water to exit the drain, external peripheral flanges for mounting the drain, and an opening for allowing water to enter the drain, the ring-shaped body having an inner sidewall and outer sidewall, and open topside, and a closed bottom or floor closing off the bottom side of the body, bridging the gap between the inner sidewall and the outer sidewall, and creating a drainage channel. The body may have an optional cover configured as a removable or replacement cover with openings. The pool drain may have optional bridging elements and flow regulating elements for greater structural support and water flow regulation through the pool drain.

Abstract: An installation tool for installing features and/or components involving a grommet onto a water containing structure assembly, and a method of use thereof, which facilitates controlled and precise application of an insertion force. The tool actively prevents or reduces the unintentional application of the insertion force onto anything surrounding the grommet. The tool, and a method of use thereof, may have an insertion force generating sub-system configured to mechanically drive a grommet-based component into the grommet, and an engagement sub-system configured to translate and impart the insertion force from the insertion force generating sub-system to the grommet-based component and the grommet. The tool may have a sturdy, stable, and slide-hammer configuration or a basic tamp configuration for use with a mallet. The slide-hammer may comprise an anvil sub-system and a hammer sub-system in a reciprocating configuration. A complimentary puller tool may be included.

Abstract: A ventilation ring for a UV water sanitizer unit that allows for adequate ventilation of heat generated by electronic components while sequestering those electronic components from water. The ring can also be made of a transparent or translucent material to allow a user to detect whether a UV lamp within the housing is operating. An improved nut for affixing a quartz tube within such a unit and improved design for draining the unit are also disclosed.

Abstract: A power supply board of the present disclosure substantially mitigates the risk of a reverse-wired lead and switch hot from the power source to the power supply board in a hazardous water-based scenario. In one exemplary embodiment, the present disclosure provides a power supply board (and a final, resulting LED controller) configured to be structurally adapted to control the load via a microcontroller and a high-power consumption switch, and to turn on and off the 120V AC power source with any duty cycle, wherein the timing at which the switch is activated is controlled to occur during a period of low voltage pressure on the negative side of the AC input voltage sine wave. All this without compromising the competing functions of the power supply board and/or the resulting LED controller.
