A narrow accessway liquid pump remotely operable multi-part, quick connect/disconnect, slide coupling comprising a fixed portion that forms a first part of a slide-together, bayonet-type coupling, a movable portion forming a second part of the coupling that is designed to support a liquid pump within an inaccessible enclosed space and that slides together with and is physically supported by the fixed portion, and a third intermediate slide valve portion intermediate both the fixed and movable portions, all three portions of the slide coupling having interiorly formed open passageways for passage of liquid therethrough which come into alignment to form an interior open liquid passageway through all three portions upon the three portions being properly seated together in an assembled relationship in an open condition;
- said three portions having complementary sealing surfaces formed thereon which come together automatically to form a liquid pressure tight seal around the aligned interiorly-formed liquid passageway through the three portions upon the movable second and intermediate portions of the slide coupling being slid into and properly seated in assembled relation within the fixed portion;
- and
- said intermediate slide valve portion further including a liquid discharge outlet slide stop valve region which normally is out of alignment with the interior open liquid passageway through the assembled portions of the slide coupling with the slide coupling in the open position but which is closed over the interior aligned liquid passageway with the slide coupling in the closed position.
