Abstract:

A recreational vehicle waste hose coupling assembly includes a coupler including a sleeve that has a first end wall, a second end wall, an inner wall and an outer wall. An inflation space is defined between the inner and outer walls. A tube has a receiving end and an insertion end and the tube is fixedly positioned within the sleeve. An air pump is fluidly coupled to an air line. The air pump is actuated to inflate the sleeve to frictionally engage the outer wall with an inner surface of a sewer pipe. A feed pipe has an inflow end, an outflow end and a bend between the inflow and outflow ends. The inflow end is removably positionable within a recreational vehicle waste hose. The outflow end is removably positionable within the receiving end.
