Drywall mud storage and distribution system

A drywall mud storage and distribution system which includes in a preferred embodiment, a mud container and pump mounted on a portable frame, a flexible mud conduit connecting the pump to a portable pressure tank for dispensing drywall mud to the pressure tank, and a second conduit leading from the pressure tank for dispensing the drywall mud through a pressure-sensitive valve, typically to a trigger-operated tape and mud dispensing device. An additional conduit fitted with a handle-operated valve leads from the pressure tank to supply drywall mud to a mud dispensing tray. The system is capable of automatically filling the pressure tank with drywall mud from the mud container by operation of the pump when a preselected pressure is reached in the pressure tank, and drywall mud of selected consistency is supplied in selected quantities on demand, to either the tape and mud dispensing device or the mud dispensing tray or both.
