ABSTRACT:
A spray flushing attachment for vehicle holding tanks, installed during initial manufacture or subsequently installed, is used to effectively and thoroughly clean out a vehicle holding tank, during the emptying of the holding tank. It is positioned in part through a hole in a holding tank end wall and secured from the outside, at a location opposite to the other end wall, in which a standard holding tank drain has been factory installed. When cleaning water under pressure is supplied through a hose to standard PVC pipe fittings attached to the spray flushing attachment, its interior horizontally diverging spray nozzle pointed toward the drain creates a wide spray across the bottom of this vehicle holding tank, which effectively cleans out the tank so no residue remains. The pressurized water flowing through the nozzle expands laterally while confined between widening arcuate nozzle sides which are covered above and left open below, and the cover terminates at a horizontal level matching the bottom of the nozzle entry orifice. The flushing attachment at its outside end has a projecting portion, matching standard available one half inch diameter PVC pipe fittings. In between these ends is an integral circular hollow housing which fits in a hole especially made in the holding tank. Adjacent to this housing is an integral external flange, inclusive of an O ring, which is secured to the holding tank exterior to firmly position all the portions of the entire spray flushing attachment.
