1. A hot water extraction system comprising a vacuum container;

  • a water tank for normally containing water up to a selective maximum operative water level therein under a vacuum condition and including a first hose interconnected to said vacuum container whereby a vacuum condition in the vacuum container provides a corresponding vacuum condition in the water tank;

    a water extractor including a second hose interconnected to said water tank whereby a vacuum condition in said water tank provides a corresponding vacuum condition in said water extractor;

    stationary flow direction controlling means stationarily fixedly disposed relative to the selective maximum operative water level in the water tank for preventing the water flowing into the water tank from the extractor up to such maximum water level under a vacuum condition from entering the vacuum container, said means being arranged relative to the extending disposition of such water level for controlling the flow direction of the vacuum induced flow into and through the water tank to travel substantially at inclined angles to such extending disposition of the water level;

    a water applicator in proximity to said water extractor;

    a line for the supply of water comprising a hose adapted to interconnect said water applicator to a conventional remote source of hot water supply; and

    a valve for metering the amount of water supplied through said water applicator.
