Abstract: A safety cover having a filter and an optional chemical dispenser, that covers and existing faceplate on a water vessel having a closed loop piping system and water pump. When the cover and filter cover an existing faceplate the cover and filter increases the vacuum on a suction line leading to a water pump by less than 5? Hg. The chemical in the dispenser releases in a metered dose of a substance having antimicrobial properties and the dose is in a sufficient amount to inhibit a growth of a microorganism in at least a segment of a water vessel. The combination of cover, filter and chemical chamber are disposable, or the filter is replaceable and the chemical in the chemical chamber is replenishable. The cover with filter and chemical chamber or just the cover and chemical chamber, or just the cover and filter are retrofitable to any existing faceplate on a water vessel having a closed looped piping system and a water pump.

Abstract: A water distribution header for a swimming pool recirculation system includes a nozzle having an arcuate face with a plurality of dispensing apertures positioned thereon. The dispensing apertures are in fluid communication with an inlet having a ball joint thereon that is coupled with the filtering system return line. The ball joint allows the angle between the header and return line to be selectively varied to assure that the nozzle is directed toward the bottom surface of the pool. Accordingly, the nozzle directs multiple, radially projecting streams of water toward the bottom of the pool thereby propelling any large debris resting thereon toward the filtering system intake drain.

Abstract: The invention comprises, in one form thereof, a water circulator that connects to the pressurized water inlet in a swimming pool. Water from the pool is pumped through the pool's filter system and into the water circulator through the pool inlet. The water circulator includes a jet tube that is vertically oriented and proximate to the pool's side wall. The pressurized water exits the jet tube through several nozzles in the jet tube. The nozzles direct the pressurized water along the side wall to thereby direct debris toward the pool outlet. The pool outlet carries the debris and water to the pool's filter system. The nozzles direct the water away from the pool outlet so that the water current travels along the majority of the side wall before reaching the pool outlet. Thus, more debris may be picked up in the current and slower moving water passes the pool outlet. The jet tube further includes one or more outlets proximate to the pool floor.

Abstract: An open-air filtration device cleans swimming pools and hot tubs in an efficient, reliable manner. An open-air filter with a suction chamber unit comprises two scrubbing brushes and an impeller powered by a motor drive. Water containing debris is pumped to a level above the swimming pool or hot tub surface. The debris containing water is discharged through a spout into a filter tube.

The spout and filter tube are, optionally, attached to a pole that manually propels the suction unit. They may alternatively be attached to a floating platform that floats on the water surface of the pool or hot tub. If filter efficiency decreases, the water level in the filter tube rises, indicating that the filter element must be replaced. A rise in water level is visually observed or detected automatically and communicated using a visible or audible alarm.

Abstract: A recessed incrementally rotating nozzle assembly is located in a wall or bottom surface of a swimming pool in fluid communication through a conduit with a source of water under pressure from a valve, which valve periodically releases water into the conduit. Each time water flows, a nozzle housing is raised to eject a stream of water. As the nozzle housing rises, it is incrementally rotated by a pin engaging a saw tooth member of a cam ring. Upon cessation of flow, the nozzle housing is retracted and during retraction the nozzle housing is further incrementally rotated by the pin engaging another saw tooth member of the cam ring. After a predetermined degree of angular rotation, a cam reverser slidably reorients protrusions guiding the pin into and out of the saw tooth members to cause the pin to be guided by the opposite side of the saw tooth members and thereby cause reversal of the direction of rotation of the nozzle housing.

Abstract: A recirculating pump system is connected to either skimmers, or a catch basin for a vanishing edge of a swimming pool, to supply water to the suction inlet of the pump system. A water distribution valve operated by an electric control system distributes water from the outlet side of the recirculating pump system to pool cleaning heads normally in accordance with a preprogrammed timed sequence. As part of each programmed cycle of operation of the water distribution valve, water is supplied to one or more pool return jets located on a side opposite the skimmer or catch basin. The return jets create moving surface currents on the water to sweep debris floating on or near the water surface to the skimmer or catch basin. An electric wind speed detector located in the vicinity of the pool and coupled to the electric control system causes the control system to override the programmed sequence in response to wind exceeding a pre-established threshold to operate the pump system to supply water to the pool return jets.
