发明名称 Waste removal conduit attachment for use with mobile sewage units
摘要 A device to reduce s and leakage from the sewage removal systems typical of recreational vehicles includes an annular coupler to provide a water-tight seal while enabling free, full rotational movement of the waste removal hose at the point of its connection to the external waste outlet for positioning until locked into the desired position, thus permitting a connection to a waste receiving tank from any direction. The use of an angled or curved pipe further increases the ability to position the device in a manner that provides the least stress at the point of the attachment of a waste-removal hose. The device is an attachment which fits between a standard external waste outlet and a standard flexible waste-removal hose. A method of making a waste-removal conduit attachment from commercially available parts is also provided.
