Abstract: A vessel for containing liquid includes a floor perimetrically surrounded by a plurality of upwardly projecting walls; at least one exit port incorporated into at least one of the walls proximate to an upper edge of the at least one wall; and a liquid circulation pump apparatus. The liquid circulation pump apparatus includes a first conduit in fluid communication with the vessel; a circulation pump positioned downstream from and in fluid communication with the first conduit; a supply conduit positioned downstream from and in fluid communication with the circulation pump; and a diverter valve positioned downstream of the circulation pump and upstream of the supply conduit. The circulation pump is adapted to pump liquid from the vessel through the first conduit and deliver liquid through the supply conduit to the exit port. The diverter valve is adapted to change a rate of flow of liquid supplied to the exit port.

Abstract: A spa system which emp loys a removable drain cover. Removal of the drain cover will cause a proximity switch to turn off the circulation pump in the spa. In a preferred embodiment, the removable drain cover has a magnet attached to it and a magnetically actuable reed switch is attached to the drain body in proximity to the drain cover. Removal of the drain cover with the magnet attached will cause the reed switch to change state which opens a circuit controlling the operation of the spa pump thereby shutting down the spa circulation system. As a result, the spa circulation system cannot be operated without the drain cover in place. This reduces the likelihood of unwanted objects being drawn into the drain. Furthermore, should the spa user's hair become entangled in the drain cover or the drain pipe, the spa pump may be turned off by simply removing the drain cover thereby permitting the entangled user to be released.

Abstract: A device for use in conjunction with a spa cover or spa cover mounted for pivotal movement to facilitate the removal of the cover away from the vicinity of the spa or spa when same is in use. In one embodiment, a bridge arm supported by two side arms is pivotally attached to a base. The bridge arm can be pivoted into position adjacent the spa cover. The spa cover folded over the bridge arm, and the bridge arm, along with the supported cover, is pivoted clearly away from the spa or spa area. In an alternate embodiment, a step elbow is provided near the point of pivotal attachment to the spa or spa to facilitate a step assisted pivoting and to provide a pivotal stop.
