A spray head assembly is provided for use in RV's, motor homes, campers and the like having gray and black water waste tanks. The spray head assembly allows for easy and thorough cleaning of the tanks to rid the tanks of sludge and debris that accumulates therein potentially causing unsanitary and unsafe conditions. Different forms of the invention are described for either retro-fitting or for factory installation on new RV's. The preferred form of the spray head assembly includes a mount having a planar flange for attachment to the outside wall of an RV waste tank. An aperture formed in the tank wall allows the spray head assembly to penetrate therethrough. By attaching a water conduit to the spray head assembly the nozzle of the spray head assembly will rapidly rotate by the pressurized water directed therein and will forcefully spray water through a plurality of channels in the nozzle. The sprayed water strikes the interior tank walls with great force, dislodging the sludge and debris buildup.
