A device for automatically flushing a dead-end of an underground municipal water distribution system includes an inlet for receiving pressurized water from the water distribution system, an outlet fluidly connected to the inlet conduit for discharging pressurized water from the inlet, and a control valve for controlling the flow of pressurized water between the inlet and the outlet. A housing surrounding the outlet redirects the water radially outwardly. An upper mounting plate locates the device within the housing. The upper mounting plate is mounted to an in-ground enclosure; releasing the upper mounting plate from the enclosure allows pulling the device from the underground water distribution system entirely from above.
