Abstract: A variable speed swim spa system wherein the user can choose between a combination of speeds with two or more pumps connected through a manifold to one or more swim jets. Check valves are used on all but the first pump to prevent backflow of water effluent and can be placed inside the manifold or between the pumps and the manifold. A user interface attached to electronic controls and operating software allow the user to program his preferred speeds with the one more jets using the two or more pumps.

Abstract: A plumbing apparatus and method for pools, spas and the like is provided. In one embodiment, a jet assembly may be provided, with the assembly comprising a jet body and one or more inside/outside fittings extending from the body. The one or more fittings are substantially hollow. At least one water supply hose is provided, with the hose sized to fit snugly inside the one or more hollow fittings or sized to fit snugly around the exterior of the one or more fittings. A plumbing system may also be provided, with the system comprising a manifold with a main body and a plurality of inside/outside fittings extending from the body. A plurality of spa accessories is also provided, with each of the accessories comprising at least one inside/outside fitting. Further, a plurality of supply hoses is provided, with one end of each hose sized to fit snugly inside or around the exterior of the manifold fittings, and the other end of each hose sized to fit snugly inside or around the exterior of the spa accessory fittings.

Abstract: A hydrotherapy jet for providing a pulsating water stream comprises a jet body, and a water inlet to allow a stream of water into the body. A water outlet allows the stream to exit the body and a movable ball within the body causes said stream of water to pulsate as it exits the body.

Abstract: A pulsating hydrotherapy jet is disclosed which has a jet body with a water inlet to allow water to flow into the body. The jet body discharges the water through a discharge member in more than one concentric pattern. A cap mounted on the body to receive the circular water patterns is also disclosed. The cap has a number of openings that form more than one concentric opening ring. Each of the opening rings align with a respective one of the circular water patterns to provide the sensation of a number of circular patterns of multiple pulsating jets. A system for providing a hydrotherapy jet to a reservoir of water is also disclosed. The system includes a reservoir shell capable of holding water with a number of hydrotherapy jets according to the invention that are mounted around the reservoir shell. A water pump system circulates water from the reservoir to the jets.
