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.

The system of claim 1 further comprising a second mount secured to the enclosure, the first mount being releasably mounted to the second mount. 3. The system of claim 2 wherein at least one of the first mount and the second mount is a plate. 4. The system of claim 1 wherein the enclosure comprises a plastic pipe. 5. The system of claim 1 wherein the outlet expels water outwardly. 6. A system for flushing a portion of an underground municipal water distribution system, the system comprising: an in-ground enclosure, at least a major portion of the in-ground enclosure being located below ground level;a flushing device at least partially positioned in the enclosure, the flushing device comprising an underground inlet adapted for receiving pressurized water from the water distribution system through a vertical push-together fitting, the push-together fitting forming a water-tight fit through a range of axial positions of a plug part and a plugreceiving part of the push-together fitting, an above-ground outlet in fluid connection with the inlet through a conduit, the outlet expelling water outwardly, and an underground control valve between the inlet and outlet, the control valve controlling the flow of pressurized water between the inlet and the outlet,a first mount locating at least a part of the flushing device with respect to the inground enclosure, the first mount being operatively releasably mounted to an upper portion of the in-ground enclosure, the system being so constructed and proportioned that releasing the first mount from the in-ground enclosure allows pulling the push-together fitting apart by sliding in an axial direction and allows lifting the flushing device, including the inlet, the conduit, and the control valve, from the underground water distribution system entirely from above, the outlet being surrounded by a housing, the housing redirecting the water discharged from the outlet outwardly to ambient. 7. The system of claim 6 wherein the housing comprises a diffuser having a plurality of openings arranged circumferentially around the housing, and a removable cover extending above the diffuser. 8. The system of claim 7 wherein the first mount comprises a plate. 9. The system of claim 1 wherein the device further comprises a second mount fixed with respect to the enclosure, the first mount being removably connected to the second mount. 10. A flushing system for flushing a portion of an underground municipal water distribution system, the flushing system comprising: an in-ground enclosure;a flushing device at least partially positioned in the enclosure, the flushing device comprising an inlet adapted for receiving pressurized water from the water distribution system through a push-together fitting, an outlet in fluid connection with the inlet, and a control valve between the inlet and outlet, the control valve controlling the flow of pressurized water between the inlet and the outlet,a bracket engaging a lower part of the push-together fitting and the in-ground enclosure to hold and position the lower part of the push-together fitting below ground in relation to the in-ground enclosure,an enlargement on the flushing device between the inlet and the outlet, anda first mount engaging the enlargement on the flushing device and locating an upper portion of the flushing device with respect to the in-ground enclosure, the first mount being operatively releasably mounted to the upper portion of the in-ground enclosure, the system being so constructed and proportioned that (a) when the first mount is mounted to the in-ground enclosure the first mount holds an upper part and the lower part of the push-together fitting together and (b) releasing the first mount from the in-ground enclosure allows pulling the push-together fitting apart by sliding in an axial direction and allows lifting and extracting the flushing device, including the upper part of the push-together fitting, the conduit, and the control valve, from the underground water distribution system entirely from above. 11. The flushing system of claim 10 wherein the push-together fitting includes a male part and a female part, at least one of the male part and female part including a plurality of o-rings. 12. The flushing system of claim 10 further comprising an intermediate mount secured to the enclosure, the first mount being releasably mounted to the intermediate mount. 13. The flushing system of claim 10 further comprising an above-ground housing, the housing comprising a removable cover surrounding the outlet and extending above and below the outlet when the first mount is mounted to the upper portion of the enclosure. 14. A flushing system for flushing a portion of an underground municipal water distribution system, the flushing system comprising: an in-ground enclosure;a flushing device at least partially positioned in the enclosure, the flushing device comprising an inlet adapted for receiving pressurized water from the water distribution system through a push-together fitting, an outlet in fluid connection with the inlet, and an underground electrically controlled valve between the inlet and outlet, the electrically controlled valve controlling the flow of pressurized water between the inlet and the outlet, andan upper mount engaging the flushing device and locating at least the inlet with respect to the enclosure, a positive attachment operatively releasably mounting the upper mount to an upper portion of the enclosure and holding the push-together fitting together, the flushing system being so constructed and arranged that releasing the upper mount from the enclosure allows extracting and disconnecting the flushing device from the underground water distribution system entirely from above. 15.
