    Abstract: A skimmer system is provided which includes a reservoir, an inlet, a reservoir pump and a weir. The skimmer system may be attached to a tank having fluid therein. The fluid in the tank defines a tank fluid surface, and the fluid in the reservoir defines a reservoir fluid surface. The reservoir receives fluid from the tank via the inlet, and the tank receives fluid from the reservoir via the reservoir pump. When the skimmer system is activated, the level of the reservoir fluid surface may be maintained below the level of the tank fluid surface. The inlet edge is located below the level of the tank fluid surface. The inlet surface may decline away from the tank to direct the fluid from the tank to the reservoir. The filter is positioned between the inlet and the reservoir to retain particulate within the fluid. The weir defines a weir edge.

  • Patent number: 6910498
    Abstract: A liquid level control system for detecting and responding to changes in the level of liquid in a container. The system includes a transmitter in radio communication with a receiver, which is in turn connected to a valve assembly. The transmitter unit is programmable to respond to changes in the level of liquid in a container and to emit a radio signal receivable by the receiver unit, which controls the release of liquid to the liquid container via the valve assembly. The signal may be suppressed by a timing circuit in the transmitter circuitry unless and until a liquid level change is sufficiently sustained. The receiver is also programmable to keep the liquid control valve open a predetermined amount of time or to close the valve upon receipt of a high liquid level signal.

  • Patent number: 6895608
    Abstract: A hydraulic suction fuse is mounted in a conventional debris collection trap of a swimming pool, spa or the like, to significantly reduce or eliminate any suction force on the bottom or side wall mounted drain of the swimming pool, spa or the like, as a result of the drain becoming essentially wholly covered by a body part of a person or other drain clogging article. Alternatively, the hydraulic suction fuse may be mounted in a compartment in line between the drain and a suction pump of a swimming pool, spa or the like. Thereby, a person captured by the suction force at the drain will be released and the person is free to move away from the drain essentially instantaneously upon contact with the drain. In one embodiment, the hydraulic suction fuse is self resetting once inflow through the drain is no longer restricted. In another embodiment of the hydraulic suction fuse, the hydraulic suction fuse may be easily manually reset.

  • Publication number: 20040187203
    Abstract: A water level controller for a pool has a water level sensor immersed in the pool. A processor detects if the sensor senses low water. A transmitter sends a radio frequency signal to a receiver if the processor detects the low water. The receiver turns on a valve to add water to the pool. The transmitter and processor are contained in a waterproof housing. A main power switch is located internally in the housing, and moves between on and off positions by inverting the housing. A wave filter timer within the processor turns on for a selected interval when the processor detects low water. The receiver has an overfill counter that turns on for a selected interval when the receiver receives the low water signal. The receiver resets the overfill counter prior to reaching the selected count each time that the receiver receives a low water signal.

  • Patent number: 6779205
    Abstract: A vacuum surge suppressor for swimming pool safety valves. These valves normally sense and then instantly relieve excessively high vacuum levels in the pool's drain line. Such high vacuum levels occur when an individual becomes trapped by the suction at the pool's drain port which is connected to the drain line. The valve relieves the high vacuum level in the pool's drain line and the suction at the drain port by bleeding air into the pool's drain line, causing the pump connected to the drain line to lose prime. However, the safety function and indeed the entire function of the pool's drain system can be disabled by a short duration vacuum surge which occurs when the pump starts. The present invention suppresses the surge before it reaches the safety valve, thereby permitting the pool and the valve to function despite the presence of such short duration surges.

  • Publication number: 20040154092
    Abstract: The invention relates to a pool skimmer including first and second tubular members that are telescopically displaceable with respect to one another, flotation means for suspending it substantially vertically in a body of water, and a tubular connector mounted on the second tubular member in liquid communication with a space defined within the tubular members and defining connector formations for connecting it in line with a hose of a pool pump. In operation in a body of water, the pump creates suction in the tubular connector and surface water flows via a weir defined by the top of the first tubular member, into the said space, via the tubular connector, and into the pool hose. The tubular members define in their side walls apertures that increasingly come into register as overlap of the members increase, thereby permitting water to flow via the apertures directly into the said space.

  • Patent number: 6754915
    Abstract: An automatic shutoff valve that can be easily installed in a swimming pool skimmer, that will prevent the flow of air through the suction outlet when the water level drops below the minimum level required to maintain buoyancy of the automatic shutoff valve's float. The valve is designed to automatically reset to normal when a sufficient level of liquid is restored in the pool and skimmer assembly, and any suction acting on the outflow portion of the valve is briefly interrupted to release the float from its position on the valve seat. During operation, the valve protects the pool's circulating pump from damage that could result from becoming air-bound ad losing its prime, as a result of sucking air through the skimmer's bottom outlet.

  • Patent number: 6747367
    Abstract: A control system for a pool and spa. Main line voltage is provided through a single line voltage service and a single ground fault circuit interrupter circuit, facilitating a ground fault test and simplifying installation. The control system acts as a power distribution system for controlling the pool and spa equipment, with a circuit board assembly including individual fuse protection devices and switching circuits. A test algorithm is included, wherein the control system is disabled from normal operation if the GFCI test fails. The pool operator manually enters a water fill command, and the controller system automatically opens the fill valve for a predetermined time interval, and then automatically closes the valve. An emergency disconnect switch is mounted near the bathing area, connected by low voltage wiring to the controller system cabinet. The controller system senses the emergency switch closure and disconnects line voltage to the line voltage loads.

  • Publication number: 20040034916
    Abstract: A swimming pool backwash control arrangement includes a timing device incorporated with a valve for controlling normal re-circulating flow and backwash flow through a swimming pool filter. The timer is constructed to be in series with the electric power circuit to the pool pump and is activated when the valve is moved to the backwash flow position. The timer functions to maintain electric power to the pump for a user-specified or a pre-set period. At the end of the period the timer will cause the circuit to open thereby disabling the pump. Power can be restored to the pump by returning the valve to its normal re-circulating flow position.
