Abstract:
1. 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, 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 engaging the flushing device and locating at least a part of the flushing device with respect to the in-ground 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 (a) when the first mount is mounted to the in-ground enclosure the first mount holds 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 inlet, the conduit, and the control valve, from the underground water distribution system entirely from above.
