ABSTRACT:
A quick disconnect coupling device for a sump pump includes a pair of vertically disposed coupling members formed of a chemically inert metallic material and coupling the discharge outlet of the sump pump to the outlet pipe for the sump. In one embodiment of the invention, each coupling member engages and is vertically slidable on vertical guide rails positioned within the sump. One coupling member is provided with vertical guide ways for receiving guides on the other coupling member which permits ready disconnection and ready reconnection of the coupling members when the sump pump is raised and lowered.
