A dispensing valve unit, adapted to be quickly filled with tap water, permitting the user to selectively rotate for dispensing selections, then pump to deliver soap and water or water only to an outlet. Composing a pair of partially interfitted tubular assemblies, forming there between an upper pump piston assembly and a lower soap valve cylinder assembly. The pump handle assembly is adapted to hold water and includes a piston and seal means and substantially right angle fill port. The cylinder assembly is operatively mounted to a mop base with cam means. The cylinder includes a locking collate and inner valve seat. Located within the cylinder is a pair of shiftable valve bodies. Upper body is a soap valve dispensing capsule, including a valve follower stem that protrudes of a ball end there of. The valve capsule is positioned to interactively engage cylinder valve seat cooperatively defining two different fluid passage way. The lower valve body includes a protruding tube cam means. First passage way: both valves are shifted up stream, lower valve pushes the ball stem end of upper valve away from cylinder seat, while holding soap valve closed. Pump water flows around past upper valve through lower valve and out tube for rinse water. Second passage way: both valves are shifted down stream, upper valve is against cylinder seat, lower valve is spaced back from upper valve. Pump water flows through upper valve, mixing with soap through lower valve out tube for soapy water.
