Abstract: Improved valve assemblies (e.g., multi-position valve assemblies) are provided. More particularly, the present disclosure provides for high efficiency multi-position rotary backwash valve assemblies. In exemplary embodiments, the present disclosure provides for a four-position rotary high efficiency valve assembly for a swimming pool or spa filter. The present disclosure provides multi-position valve assemblies having infrequent maintenance and allowing for user-friendly service. The present disclosure provides for improved multi-position valve assemblies and related features, systems and methods of use. Improved, convenient and effective systems and methods for utilizing improved multi-position valve assemblies (e.g., high efficiency multi-position rotary backwash valve assemblies) are provided. The valve assembly can be utilized in fluid systems as a flow control assembly (e.g., as a backwash valve associated with a pool or spa filter).

Abstract: Exemplary embodiments are directed to deck jet systems including an adjustable cover and flexible finishing cap. The deck jet systems include a housing with threads formed on an inner surface of the housing. The deck jet systems include an adjustment ring with threads formed on an outer surface of the adjustment ring complementary to the threads of the housing. The deck jet systems include an adjustable cover, the bottom surface of the adjustable cover being inserted into the proximal end of the housing and supported by a top surface of the adjustment ring. Engagement of the threads of the housing and the adjustment ring and rotation of the adjustment ring relative to the housing can vary an elevation of the adjustment ring relative to the housing which, in turn, varies an elevation of the adjustable cover relative to the housing. Exemplary embodiments are also directed to methods of adjusting a deck jet system.

Abstract: Disclosed herein is a filter for use in connection with a swimming pool or spa. A device is provided that has a tube inlet at the top of a vessel. A lower end of the device is connected directly to an outlet of the filter. The device is designed to divert all or the majority of the fluid to move to the top of the filter before exiting the vessel.
