ABSTRACT:
A device for use as a convenient, easy-to-use, and inexpensive pump for pumping water is disclosed which uses water pressure from a standard garden hose connected from a tap to the pump apparatus as the motive power to pump between seven and eleven times the volume of the water from the garden hose from a reservoir into a discharge hose which is any of several different standard sizes and which is connected to the pump apparatus. The water from the garden hose flows into the pump through a pump inlet having a reduced diameter venturi, which increases the velocity of the water, into a pumping chamber with the resulting drop in pressure creating a vacuum in the pumping chamber. The vacuum in the pressure chamber draws water from a reservoir the pump is placed in through a reservoir inlet chamber into the pumping chamber in the pump body, and the water exits the pumping chamber through a pump outlet located on the opposite side of the pumping chamber from the pump inlet.
