The manifold further includes two arcuately spaced tabs, each subtending arcs having different arcuate lengths. The manifold is positioned such that the tabs mate with at least two slots of a lock ring of the waste collection unit so as to cause the opening of the manifold to be, upon insertion into a bore of the waste collection unit, in a specific rotational alignment in the bore. The manifold is rotated within the bore to cause a valve disk to move between a first position in which the valve disk blocks fluid flow through the receiver and a second position in which the valve disk allows fluid flow through the receiver.
