  • Patent number: 10344491
    Abstract: A pool drain for flush mounting in the surface of a swimming pool includes a central hub and elongated drain ports in fluid communication with the central hub. The elongated drain ports extend radially away from the central hub. The surface material individually surrounds the central hub and elongated drain ports when the pool drain is installed in the surface material. Internal dividers are located between the central hub and the elongated drain ports. The internal dividers are positioned so that they direct fluid away from the central hub, around each of the internal dividers and back toward the central hub. A water stop surrounding the central hub and elongated drain ports anchors the pool drain in the surface and prevents leakage.

The disinfectant dispenser is adapted to enable infinite adjustment to the level of disinfectant dispensed into the normal flow of the pool water. The skimmer includes a valve that is used to adjust the flow of water distributed to the disinfectant dispenser. The flow rate of water entering the dispensing chamber is controlled by the valve, which controls the water level within the dispensing chamber. The amount of water exiting the dispensing chamber is controlled by a vertically extending elongated flow slit. The higher the water level in the dispensing chamber causes more exposure to the chlorine tablets, increasing the chlorine level in the dispensing water. Chlorinated water exits the flow slit and enters the skimmer main chamber.

    Abstract: A pool fluid control system utilizes a fluid collection tank having an intake enclosure extending therefrom. The intake enclosure has an open grate which is configured to be positioned flush with the pool wall. Water which accumulates between the pool wall and the liner flows through the grate, into the intake enclosure, and then into the collection tank. A sump pump or other submersible pump within the collection tank then discharges the water out of the collection tank for disposal at a location away from the pool. This constant monitoring and then automatic removal of unwanted water from the space between the liner and the pool wall serves to maintain the integrity of the liner in relation to the wall.

  • Patent number: 8603330
    Abstract: A water diverter assembly is positionable in a skimmer chamber between a well and a pool. A bar has opposed ends removably received in and supported by the chamber. First and a second similarly configured plates have interior ends with first radii of curvature adjacent to the well and exterior ends with second radii of curvature greater than the first radii of curvature adjacent to the pool. Regions join the bar and the plates. The plates are closest together at the interface of the interior and exterior ends. The plates increase their separation at the interface during operation and use in response to the flow of water between the plates.

  • Publication number: 20130152298
    Abstract: A pool drain cover includes a center hub which can be rotated with respect to an outer portion. A twisting of the center hub causes multiple (e.g., three or more) engagement arm assemblies to extend such that their distal ends engage the inner surface of a pool drain pipe, thereby holding the pool drain cover in place. The distal ends of the engagement arms may be provided with an anti-slip coating such as, for example, vinyl, rubber, etc., and/or an anti-slip finish. Alternatively, a metal (e.g., stainless steel) tab extending from the distal end of each of the engagement arm assemblies can be provided. The engagement arm assemblies can be released by twisting the center hub in the opposite direction, thereby permitting the pool drain cover to be removed.

  • Patent number: 8453275
    Abstract: A combination bathtub and spa includes a tub enclosure that is adapted to contain a quantity of water, a drain having a drain valve that may be opened to drain water from the tub enclosure or closed to retain water therein, a supply system for supplying water to the tub enclosure, and a lid that is adapted to removably cover the tub enclosure. The combination bathtub and spa also includes a pump having an inlet and an outlet, a suction line that provides a path for water from the tub enclosure to the inlet of the pump, a jet nozzle that is located in the sidewall of the tub enclosure, and a jet nozzle supply line that provides a path for water from the outlet of the pump to the jet nozzle. A filter is provided to filter the water that flows into the tub enclosure, as well as a heater for heating the water that flows into the tub enclosure. A control valve is adapted to open to allow water to flow through the filter or to close to stop the flow of water through the filter.

  • Patent number: 8409434
    Abstract: Treatment devices for fluid such as water are described. Principally (although not necessarily exclusively) designed for use as chlorinators, the devices may divert water flowing in conduits into the devices for treatment and subsequent return to the flow stream. A return tube of the device may be designed to create vortex action, using a pressure differential to evacuate treated water from the device back into the conduit.

  • Patent number: 8382977
    Abstract: A pool has an opening formed with upper and lower surfaces and first and second side surfaces. A chamber located interiorly of the opening has a cylindrical well with a vertical axis. A first diverter plate has an exterior edge adjacent to the first side surface and an interior edge between the opening and the well. The first diverter plate is arcuate with a vertical axis of rotation adjacent to the first side surface. A second diverter plate has primary and secondary sections. The primary section has an exterior edge adjacent to the second side surface and an interior edge between the opening and the well and is arcuate with a vertical axis of rotation adjacent to the second side surface. The secondary section is located adjacent the primary section with a vertical axis of rotation essentially co-extensive with the axis of the well.

  • Publication number: 20120272444
    Abstract: A drain sump includes a secondary chamber for providing an alternate source of water for the main drain to pull water from, thereby limiting the suction force created when the flow of water is obstructed. In a preferred embodiment, the two chambers within the drain sump are partitioned by a septum wall, which provides a passage for a drain pipe extension at the center of the septum wall and further includes a plurality of venting channels for ideal water flow between the two chambers. Each chamber is in open fluid flow communication with the pool water via the drain grate. Relief hole passages are included on the drain pipe extension for providing open fluid communication between the secondary chamber and the water flow passage. The drain pipe extension may further include two 90 degree bends for restricting access to the water flow passage of the drain pipe extension.

  • Patent number: 8281427
    Abstract: The drain apparatus of the present invention is designed and configured to prevent the entrapment of a person by the suction or vacuum forces of a drain in a swimming pool, spa, or any other large body of water with a recirculation system. The drain apparatus of the present invention has a spring biased plunger that immediately closes the drain of a swimming pool, spa, or any other large body of water when a substantial portion of the drain cover is blocked or restricted. By closing the drain, the drain apparatus of the present invention eliminates any vacuum or suction pressure at or underneath the drain cover that entraps a person thus allowing the person to break free easily and immediately without any time delays.
