A pool drain cover including a cover assembly and a wires assembly. The cover assembly includes a cover and a bump, wherein the bump is a bubble-shaped portion integrally formed on the cover. The cover is placed over the pool drain cover to prevent collecting worms into the main drain pool system, thereby the cover may sink into the water and be positioned by means of a rope and a plurality of ropes included in the wires assembly. The user may handle the rope until reaching a predetermined position over the pool drain cover and pulling the rope to remove the cover from the pool drain cover when the user may consider appropriate.

A hydraulic valve engages a through opening delimited through a bottom wall of a tank for a liquid and comprises a cage element connected inside the bottom wall, a shutter movably housed in the cage element, a hollow connection element which hermetically engages the through opening delimiting a passage that passes through the hydraulic valve, wherein the hollow connecting element comprises an engagement portion which extends into the through opening and defines a passage opening selectively occludable by means of a shutter as a function of the quantity of liquid in the tank, wherein the hollow connecting element comprises radial notches which define respective passages for a liquid sucked out of the tank through which the formation of a vortex is prevented and the sucking in air.

A drain valve comprises a valve shell and a valve core which comprises an inner core and an outer core. In the process of draining and closing, the outer core and the inner core of the valve is rotated through operating the handle nut and a rotating part, so as to realize the accurate control of the position of the valve core. When draining water, the first through hole and the second through hole are aligned, and then water is drained to the water outlet pipe through the outlet of the valve core, so that the drainage is smooth; when closed, the valve core is completely pushed into the interior, and the internal water is squeezed out, thus reducing the possibility of residual water, effectively preventing the drain valve from being frozen, and ensuring the normal use of the drain valve in cold climates.

The present disclosure provides a skimmer basket assembly. The skimmer basket assembly may include a basket, the bottom of which may include one or more flaps. A handle may be connected to the basket via one or more connectors. The handle may include a trigger mechanism that is mechanically linked to the one or more flaps of the basket. The trigger mechanism may be configured to operate the one of more flaps of the basket upon manipulation of the trigger mechanism. The skimmer basket assembly may include a lid that is slidingly connected to the one or more connectors. The lid may be configured to receive the handle therein and substantially cover a top opening of the basket.

An inflatable pool is includes a floor drain having a drainage conduit and two sealing plug. The drainage conduit includes a midsection pipe having an oblong cross section, an inlet cap having a truncated profile, and an outlet cap that transitions from the oblong profile of the midsection to a cylindrical profile.

A sump drain includes a ring-shaped chamber having an inner sidewall with a diameter of at least about 18 inches and an outer sidewall, and a circular opening between the sidewalls preferably about an inch wide and optionally having a grid cover. Preferably the inner sidewall has a number of ports extending inwardly to radial conduits to a central hub for tying into a pool or spa filtering system, with the central hub operating as a clean out and having a removable cap. Upon installation, plaster substantially fills the space between the chamber and the central hub, such that the sump drain attractively blends in with the pool or spa floor. When installed, the top opening is preferably substantially flush with the pool or spa floor while being safely unblockable. And the sump drain preferably further includes channels both outboard and inboard from the chamber top opening and around the central hub, to help prevent water from passing through the plaster into the shotcrete of the pool or spa.

A system and a method for performing an operation related to a swimming pool or spa is provided. The method comprises receiving a selection of an area of the swimming pool or spa on a digital map of the swimming pool or spa rendered at a mobile device or a controller, and identifying one or more components of the swimming pool or spa corresponding to the selected area. The method further comprises receiving a selection of at least one component from one or more components on a digital map of the swimming pool or spa rendered at the mobile device or the controller, and transmitting a command to activate the selected at least one component of the swimming pool or spa to perform the operation related to the swimming pool or spa.

A visual light communication system is disclosed.

A method for treating water in a spa or a hot tub includes, for example, suspending a water treatment dispenser from an upper end of a filter cartridge disposed in a skimmer of the spa or the hot tub. The dispenser includes a water treatment material. A supply of water is passed from the spa or the hot tub into the skimmer and through the filter cartridge so that the dispenser suspended in the filtered water in the filter cartridge is operable to dispense the water treatment material from the dispenser, and a supply of treated filtered water from the filter cartridge is returned to the spa or the hot tub. A cover, for example, may be employed when the dispenser is not used.

A visual light communication system is disclosed.
