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.

Abstract: A velocity reducing filter port is provided herein. More specifically, provided herein is a pool filter comprising a filter housing having a sidewall and a bottom wall defining an inner chamber, an inlet section positioned in the sidewall of the filter housing, an outlet section positioned in the sidewall of the filter housing, and a flow controller attached to the inlet section, the flow controller having a flow controller inlet, a flow controller outlet, and a wall therebetween, wherein the flow controller inlet has an inlet cross-sectional area and the flow controller outlet has an outlet cross-sectional area greater than the inlet cross-sectional area.

Abstract: Exemplary embodiments are directed to venturi bypass systems that generally include a fluid inlet and a fluid outlet. The systems can include a venturi path disposed between the fluid inlet and the fluid outlet. The venturi path can include a venturi defining a venturi inlet and a venturi outlet. The systems can include a bypass loop connected to the venturi path at a joint upstream of the venturi outlet. The systems can include a separation tube connected to the venturi outlet. The separation tube can extend fluid flowing through the venturi path downstream of the joint at which the bypass loop connects to the venturi path. Exemplary embodiments are also directed to methods of regulating fluid flow through a venturi bypass system.
