  • Publication number: 20040205886
    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.

  • 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: 20020083517
    Abstract: A skimmer protector with integral blow tube is a hollow, substantially closed, blow-molded body of resilient resin material having a cylindrical projection on one end with external screw threads for threading into the intake pipe of a swimming pool skimmer with an open integral tube running from and through said screw threaded portion to an opening elsewhere on its blow-molded body. The cylindrical projection on the body of the device is intended and designed to be threaded into the intake pipe or other part of a pool skimmer. When connected thereto, the skimmer protector is positioned to absorb/buffer the forces exerted by the expansion of ice as it freezes within the walled regions of the skimmer. The aforesaid integral tube serves to create a sealed air space between the tube and the outer walls. This sealed air space helps to resiliently stiffen the body of the skimmer protector, allowing it to better perform its function in absorbing ice expansion pressure.

  • Patent number: 6408452
    Abstract: An automatic shut-off valve for installation on a swimming pool or spa main drain. The automatic shut-off valve has a ball and ball spring between a diaphragm and a housing. The diaphragm is made of resilient material. Downward force on the diaphragm urges the ball into sealable engagement with a valve seat in the housing. During operation, a swimmer covers sufficient diaphragm base apertures so that the diaphragm center is moved downwards as urged by the main drain suction, towards a swimming pool or spa main drain over which the automatic shut-off valve is mounted. The downward motion of the diaphragm urges the ball into sealable engagement with a valve seat in the housing, where it is securely held by the main drain suction. In this fashion, the ball is entrapped instead of the swimmer, thus avoiding possible disembowelment and/or drowning on the part of the swimmer. Back-up shut-off function is provided by a cap spring-loaded into a closed position whence it migrates should the ball become dislodged.
