ABSTRACT:
A four component sewer coupling arrangement for recreational vehicles and the like is disclosed including a recreational vehicle sewer outlet fixed to the vehicle, a threaded closure cap for closing the outlet when the vehicle is in transit, a tether line connecting the closure cap and outlet so that the closure cap is not inadvertently lost or mislaid, and a flexible drain hose having a threaded connector at one end for connecting the drain hose to the outlet when the closure cap is removed so that an end of the flexible drain hose opposite the threaded connector may be connected to a sewage disposal location for discharging sewage from the recreational vehicle by way of the flexible drain hose to the sewage diaposal location. A quick release spring coupling may be substituted for the threads. Both the closure cap and threaded connector are provided with means for facilitating their tightening and loosening relative to the fixed outlet thereby providing a good seal to the outlet.
