Abstract: A telescopic drain hose assembly. The assembly includes a drain conduit having a tank coupler coupled to a first end and an end piece coupled to a second end. The tank coupler is configured for coupling to a grey or black waste discharge port, such as that of a recreational vehicle. The endpiece includes coupling elements for coupling with a pipe elbow or similar attachment. A handle is provided on the endpiece for positioning the endpiece in proximity to a waste receptacle port. The drain conduit is disposed within an outer housing comprised of a telescopic tube and a flexible sleeve. The flexible sleeve is adjacent the first end of the drain conduit and enables flexure or bending of the assembly.
