  • Pool suction valve
    Patent number: 8128814
    Abstract: A valve system for insertion between a cleaner hose and a pool suction line is mounted in a wall of the pool or skimmer box and comprises a valve with a gate pivoted in a housing which receives the end of the cleaner hose when the gate is open which is thereby juxtaposed in line with the pool suction line located in the pool wall or skimmer box. The juxtaposed ends of both the cleaner hose and the pool suction line have mating tapers and the valve rotates so that the tapered end of the inserted cleaner hose rotates into sealing engagement with the tapered end of the pool suction line. Further the gate of the valve closes automatically when the cleaner hose is withdrawn.
