A pool strainer basket insert system and method are contemplated in which a high porosity, coarse fibrous mass is inserted in a pool skimmer basket. Via optimization of the material properties of the fibrous mass and configuration such that approximately 50% of the fibrous mass is located above the waterline and 50% below the water line the problems of the prior art may be solved via the retaining properties of the fibrous mass, enabling insects and small organic matter to be retained and preventing their migration back to the main body of the pool.

A bubble generator including a container having a side wall and a top wall defining a cavity. An insert is located within the cavity defining a gas path with a trap portion. The gas path being in communication with an exit in the container. The cavity including an opening receiving a gas accumulating within the cavity, the gas path allowing the accumulating gas to escape through the exit once the accumulating gas reaches a predetermined level proximate the trap portion.

Disclosed is a device for analysing water and a swimming pool equipped with such a device. The device includes: an analysis chamber provided with at least one water inlet and at least one water outlet; a sealed housing adjacent to the analysis chamber and isolated from the analysis chamber by a partition; a data processor housed in the sealed housing; at least one probe electrically connected to a data input of the data processor; an electrical power supply electrically connected to a power input of the data processor, the electrical power supply having an electrical generator provided with a turbine housed in the analysis chamber, the electrical generator being electrically connected to the data input of the data processor. The device is useful for monitoring the sanitary state of the water of a swimming pool.

A sanitation device for cleaning a body of water in an immersion pool of a mikvah has a housing, a driving member and a bypass passageway. The housing includes an inlet, an outlet and internal liquid passages that communicate between the inlet and outlet. The driving member is arranged to urge flow of liquid through the internal liquid passages by exerting thrust upon liquid flowing through the driving member, wherein at least part of the liquid flowing through the liquid passages bypasses flowing through the driving member by flowing through the bypass passageway towards the device's outlet.

An article of manufacture for providing a water salinizer to add salt to pool water is disclosed. The water salinizer includes a barrel having a sidewall, a convex bottom, an angled sidewall between the convex bottom and the side wall, and an opening is a top surface for dissolving material into water, an input port coupled to the angled sidewall and being configured with the convex bottom to direct an incoming pressurized water stream and salt around the barrel along the angled sidewall, and a discharge port coupled to the sidewall about the opening in the top surface on an opposite side of the barrel from the input port.

Systems and methods of detecting when an automatic swimming pool cleaner (APC) has contacted a main drain cover or other object protruding from a surface of a swimming pool are described. An APC may include equipment for detecting a change in its pitch or yaw (or both its pitch and yaw). Changes in pitch and yaw may be determined as a function of time, identifying encounters of the APC with certain protruding objects.

A skimmer assembly includes a housing, a first inlet, a first outlet, a second inlet, a second outlet, and a valve. The housing includes a first chamber portion, a second chamber portion, and a divider wall. The divider wall is operable to inhibit fluid communication between the first chamber portion and the second chamber portion. The first inlet and the first outlet are in fluid communication with the first chamber portion. The second inlet and the second outlet are in fluid communication with the second chamber portion. The valve is operable in an open state and a closed state. The valve is configured to (i) allow a flow of fluid into the second chamber portion in the open state and (ii) inhibit the flow of fluid into the second chamber portion in the closed state.

A skimmer assembly includes a housing, a base member, and a carriage. The housing includes a plurality of walls defining a chamber. The base member includes a first sidewall and a first hub. The first sidewall extends from an upper surface of the base member. The first hub extends from a lower surface of the base member. The lower surface is opposite the upper surface. The base member is configured to receive the housing such that the first sidewall at least partially surrounds the housing. The carriage includes a second sidewall and a second hub. The second sidewall extends from an upper surface of the carriage. The first hub extends from a lower surface of the carriage opposite the upper surface of the carriage. The first hub is configured to rotatably receive the second hub.

A filter assembly for filtering water in spas, swimming pools, hot tubs and whirlpools, having a first or outer filter element, a second or inner filter element removably installed within the outer filter element, a first coupling member associated with the outer filter element, a second coupling member associated with the inner filter element, the first and second coupling members engaging one another to connect the inner filter element with the outer filter element, and a releasable detent arrangement resisting disengagement of the first and second coupling members from one another. The outer filter element includes a filter medium for mechanically removing particulates from a fluid to be treated and the inner filter element includes a filter medium containing fluid purifying particles.

Communications capabilities are supplied to components of pool water recirculation systems, even if the components lack electrical power or supply wires. Capabilities may be furnished by wireless RF devices that connect to existing fittings or ports of the components, for example. The devices are configured to obtain desired information relating to the components (or the water within them) and transmit the information remotely for processing or consideration.
