ABSTRACT:
An apparatus for discharging sewage from a holding tank on a travel trailer or the like to a sewer inlet includes a flexible inlet coupling section for connecting to the discharge fitting on the holding tank, an L-shaped fixed outlet coupling section for insertion into the sewer opening, and a telescoping tube section connected to the inlet and outlet coupling sections. The joints or connection points to the flexible inlet coupling sections are sealed by hose clamps, and the connection between the tube sections and the connection between one end of the tube sections and the outlet coupling section are sealed with locking couplings having "O" rings. The flexible coupling and telescoping section accommodate various positions of the holding tank relative to the sewer inlet. A rigid tube section can be inserted between the telescoping tube section and the outlet coupling section to further increase the length of the sewage discharge apparatus.
