  • Flow enhancing jet fitting
    Patent number: 4941217
    Abstract: A jet fitting for a hydrotherapeutic receptacle includes an internal chamber which functions as a mixing chamber as well as a suction chamber. More particularly, a primary stream of water is supplied to the mixing chamber in such a manner that a low pressure condition is created within the mixing chamber for the purpose of entraining a secondary stream of water which flows from the hydrotherapeutic receptacle to the mixing chamber. The combined streams exit the fitting together so as to increase its discharge flow rate.

  • Skimmer vacuum filter apparatus
    Patent number: 4798670
    Abstract: A filter includes a housing which removably receives a filter cartridge adapted to remove fine and coarse debris from water flowing therethrough. The filter is removably mounted in a skimmer well of a swimming pool in place of a conventional strainer basket. The interchangeability of the filter and the strainer basket permits them to be used selectively such that the strainer basket can be used during a pool skimming operation and the filter can be used during a pool vacuuming operation.
