An illuminated waterfall unit for a spa or pool comprises a manifold body with a water outlet that forms outflowing water into a waterfall. An optical probe is positioned within the manifold body to receive light from a light source, preferably an optical fiber, and to illuminate the waterfall by optical transmission through the outlet body. The probe is preferably positioned so that is also illuminates the waterfall directly.

Pool/spa waterfall unit with fiber optic illumination

A reservoir component is disclosed that provides fiber optic illumination to the water within the reservoir. The reservoirs of water include pools, spas, tubs and the like, and their components include jets, returns, drains and skimmers. An elongated and transparent probe is mounted within the component and extends from the rear of the component toward the front. The probe is open at the rear of the jet and is hollow through most of its length to receive and house an optical fiber. The light emitting from the end of the fiber passes through the end of the probe and out of the component. The probe can protrude from the front of the component and transmit the light directly into the water. Alternatively the probe can transmit short the components front end which is constructed of transparent material to transmit the light from the probe into the water.

A hydrotherapy jet system has a segmented outlet that extends from the jet body in response to a water flow through the jet and retracts when the flow stops. Water flows into the jet body, where it is directed into a nozzle that tapers to accelerate the water into a venturi jet that can then be aerated if desired. The water then enters the segmented outlet, which is urged to a retracted position within the jet body by a spring. The pressure from the water causes the outlet to extend from the jet housing against the spring pressure, compressing the spring. When extended, the outlet provides a stream of warm or aerated water to a reservoir such as a spa, pool or bathtub and the outlet can be manipulated to direct the stream. When the flow of water is stopped the spring expands and causes the outlet to retract into the jet body.

The system includes a jet, a rotating member or &ldquo;eyeball&rdquo; housing a series of discharge nozzles that can be adjusted to vary the location of an outlet flow stream as well as the direction and speed of the eyeball's rotation. A high pressure water jet flows into the eyeball and exits through the discharge nozzles. Depending upon the adjustable orientation of the nozzles, relative to the rest of the eyeball, the eyeball can be rotated clockwise or counter-clockwise, and at varying speeds. The discharge nozzles are further positionable to permit them to be displaced in a common direction.

Adjustable multi-nozzle rotating hydrotherapy jet system

The system includes a jet, a rotating member or 'eyeball' and a diverter cap formed with a number of bore holes positioned at a common radius from the center of the cap. The jet produces a high pressure water jet that flows through the eyeball causing it to rotate at a high speed and discharge the jet in a circular pattern that impinges on the bore holes. The bore holes are formed in the diverter cap so that the upstream intersection of the bore holes forms a series of ridges that divert the rotating jet into the appropriate bore hole(s) without blocking the jet and producing a back flow and are aligned with the rotating eyeball to minimize pressure losses experienced by the jet. Together the rotation speed and bore hole design produce the sensation of a number of simultaneously pulsating water jets that are directed into the spa or tub. The system has the added advantage in that its design results in low pressure losses.

Pulsating hydrotherapy jet system

A hydrotherapy jet system has a rotatable multi-nozzle unit containing a series of individual nozzles that are selectable, while water is flowing through the system, to present different flow affect. Water flows into a jet body where it is diverted into an into a passageway that is non-coaxial with the jet body. Within the passageway is a venturi which aerates the water stream. Leaving the venturi, the water enters the multi-nozzle unit, flows through the nozzle in line with the passageway, exiting the jet body into a spa or tub. The nozzles are selectable by the rotation of the nozzle carrier to provide different flow affects to the user.

Selectable hydrotherapy jet system

A pool pump controller includes a pneumatic pressure sensor having at least one port disposed to react to negative pressure within a pool's pump intake chamber. The sensor input port, which includes a check valve, is connected to a pump control switch through a pneumatic tube. The pump control switch combines aspects of a diaphragm switch and an opto-interrupter to provide high-reliability control of the pump motor in a watery environment.
