ABSTRACT:
A dump fitting on the discharge end of a sewer hose leading from the waste holding tank of a recreational vehicle prevents the hose from jumping out of a sewer drain under the influence of effluent being discharged through the hose. The fitting is in the form of an elbow with one limb received in the discharge end of the sewer hose and the other limb forming an outlet for receipt in the sewer drain. The fitting is of sufficient weight to resist the thrust of effluent flowing through the hose and tending to lift its discharge end. The fitting may be a one-part plastic molding or a two-part fit-together molding.
