Abstract
A cleaning and storage implement for cleaning and storing sewer hoses used to discharge the contents of holding tanks of recreational vehicles. An elongated plastic tube has a length and first and second ends, with a water supply conduit fitting on the first end and a nozzle that sprays in a conical spray pattern on the second end. An adjustable positionable stop on the tube near the first end in the form of a disk has a hole sized so as to receive the tube in an adjustable friction fit. A hand grip on the tube is located between the fitting and the stop, and a retainer hook on the tube is located near the second end. A compressible hose may be cleaned and stored by connecting a cleaning water supply conduit to the first end of the tube, supplying water through the tube from the supply while passing the second end of the tube into a first end of the hose to clean the hose by a spray of water from the nozzle at the second end of the tube. The hose is compressed against the stop, and upon compressing the hose to a length comparable to the distance between the stop and the retainer, the second end of the hose is retained with the retainer hook.
