An improved drain for an above-ground pool is disclosed. A variety of above-ground pool types are considered. Above-ground pools must be drained after use before being stored in a lengthy and time-consuming process. The improved drain can advantageously remain open during the draining process allowing for improved drainage. The drain can comprise a plug member and a locking member. The plug member can be configured to attach to the locking member when open. This and other embodiments are disclosed herein.

An in-floor pool cleaning system for controllably directing pressurized water from a pump to surface regions of a pool or spa. The system comprises a plurality of zone outlets each terminating at a nozzle disposed in a surface of the pool or spa and each controlled to an opened condition responsive to a control signal supplied to an associated zone valve. A controller supplying the control signals to each valve according to a schedule that sets forth the opened-state time, the closed-state time, and the opened state duration for each zone valve. The valves are individually controllable. A normally-opened bypass outlet is controllable to a closed state when one or more of the zone valves is in an opened state, and controllable to an opened state to supply water to the pool responsive to detection of a system over-pressurization or a system loss of power.

A vinyl drain cover assembly for a pool or spa is provided. The drain cover assembly has a vinyl insert that allows the drain cover assembly to blend in visually with the surrounding vinyl liner of the pool or spa. The insert is exchangeable with another insert having a different appearance. The drain cover assembly supports the insert and prevents the insert from being sucked into the drain.

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 used to monitor and control a pool using a visual light communication system is disclosed.

An overflow system for a recreational pool includes a drain configured to be mounted to a bottom of the recreational pool, and a drain pipe configured to extend substantially horizontally from the drain under a perimeter wall defining a boundary of the recreational pool to outside the boundary. The system also includes a standpipe configured to be positioned outside the boundary and having a first end and an open second end. The first end is coupled to the drain pipe and the second open end has an overflow elevation between a normal water level elevation for the recreational pool and a top of wall elevation of the perimeter wall. In addition, the system includes a recirculation pipe having a first end in fluid communication with the recreational pool and a second end in fluid communication with the standpipe proximate the second open end.

A visual light communication system is disclosed.

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.
