Abstract: A swivel component allows a power cable to a pool or spa component, to swivel when the inductive power couplings are coupled. The couplings include a first inductive coupling that can be positioned within and/or mounted into a wall fitting, a second inductive coupling that inductively couples with the first inductive coupling, a swivel component attached to the second inductive coupling for allowing the second coupling to swivel with respect to the first inductive coupling, and a retainer ring that engages with the wall fitting and retains the first and second couplings and the swivel component in position within the wall fitting. A power cable is connected at one end to the second inductive power coupling and at an opposite end to a pool or spa component, such as an electric cleaner. Swiveling of the second power coupling relative to the first power coupling reduces kinking of the power cable.

Abstract: Improved flow control valve assemblies for fluid systems (e.g., pools or spas) are provided. Advantageous flow control valve assemblies for pool/spa cleaners (e.g., suction pool/spa cleaners) are provided. The present disclosure provides for flow control assemblies for suction pool/spa cleaners, with the cleaners utilized in conjunction with a variable speed pump. A manual valve set-up can be removed from the system, and an advantageous flow control valve assembly can be provided to automatically regulate the flow/suction to the cleaner. The improved flow control valve assembly thereby provides regulated flow to the cleaner, so that if the cleaner remains in the water at low pump speeds, when the pump is later operated at a higher speed the cleaner will function as designed. When there is flow/suction below the desired operating parameters of the cleaner, the pump will operate as desired, and the cleaner is stationary.

The wireless communication subsystem is configured to receive one or more control parameters from the device, and the controller controls operation of the variable speed pump based on the one or more control parameters.

Abstract: A first valve of a manifold for a fluid distribution system (“FDS”) regulates fluid flow to a first fluid handling device (“FHD”). A second valve of the manifold may communicate with a second FHD, reservoir, or recirculation line. A target flow condition for the manifold may be determined by a manifold control system (“MCS”) based on a device setting received from the first FHD. The MCS may determine an operation of the FDS based on the target flow condition, fluid flowrate, and supply device operational state. The operation may include the MCS controlling the supply device, first valve, and/or second valve to change the flowrate. The MCS may continuously operate a valve to maintain the target flow condition once exhibited. Fluid distribution systems, systems and methods for turning over an FDS including a manifold, and systems and methods for controlling operations of an FDS including multiple manifolds are also provided.
