Abstract: A water flushing and sampling device (1) comprising a valve (33) operable to flush water from a subterranean source through the device. A turbine (73) downstream of an outlet nozzle (37) is operable to generate electricity when water is flushed through the device. An enclosure (13) contains the valve, a temperature sensor (81) operable to sense temperature within the enclosure, a heater (77, 83) operably connected to the turbine and being operable to heat the enclosure, and a control system (91) operable to open the valve to cause the turbine to operate the heater when the temperature sensor indicates the approach of a dangerously low temperature.

Abstract: A water meter resetter incorporates as a principal component a plastic body having six fittings lying in a common plane. A primary inlet and primary outlet are coaxially aligned on first and second opposed walls. A secondary outlet and secondary inlet are coaxially aligned on the opposed walls. In use, a first horn is rotatably attached to the secondary outlet, and a second horn is rotatable attached to the secondary inlet. A water meter is attached between the horns. Because the horns are rotatable about a common axis at each of their ends, the meter can be offset from the supply pipes at continuously variable heights. In an embodiment, the secondary inlet and outlet are internal, and the horns are held in a fluid-tight slip joint formed by internal O-rings. The height of the meter may optionally be locked by the use of an angle holder.

Abstract: A reconfigurable water flushing and sampling device which permits the same device to be utilized as a manual flusher, a continuous flushing device, an automatic flushing device, or a sampling station, or combinations thereof.

Abstract: 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.

Abstract: A drain ring adapted for use in a device for flushing a dead-end of an underground municipal water distribution system includes a pair of annular seals and a channel between the seals, an outlet passage extending from inside the ring to the channel, and a flapper adapted to close the outlet passage under the influence of at least one of pressure and flow. The drain ring is removably positioned between a shut-off valve and an outlet of the device.

Abstract: A device and method for automatically flushing hydrants. The device is installed externally to an existing hydrant. The device comprises a nipple having an internally threaded collar for attaching the device to a hydrant outlet, a valve, a control for automatically operating the valve, and a lockable box containing at least the valve, the box having an outlet for allowing water from the hydrant to pass from the valve to the exterior of the box. The box functions as an enclosure and may be of any desired configuration.

Abstract: A device and method for installing yard hydrants which renders the yard hydrant easily installed and replaced. The device includes a buried adapter, a sleeve, and a cap. The buried adapter has an inlet for attachment to a buried water system pipe, an outlet for attachment to a valve body of a yard hydrant, a peripheral wall for attachment to a vertical sleeve, and a drain hole. The sleeve is preferably a pipe sized to receive the valve body of a yard hydrant. The cap illustratively includes an internally threaded collar screwed onto the top of the sleeve and two cover pieces locked to the collar against rotation, each cover piece having an upturned flange with semi-cylindrical recesses which clamp the standpipe of the yard hydrant between them. The device is attached to an underground water pipe, the yard hydrant is then inserted into the sleeve and removably screwed onto the adapter, and the cap is applied to lock the yard hydrant in place.

Abstract: A water distribution system includes flushing hydrants having buried valve assemblies and a removable top stock carried from valve assembly to valve assembly. A vertical marker replaces the top stock when the hydrant is not in use. The buried valve assembly includes a valve urged closed by water pressure and an actuator rod extending through a spider in the top of a vertical barrel. A lock nut on the upper end of the actuator holds the valve closed even if water pressure is lost. The upper end of the vertical barrel includes an internally threaded adapter. The top stock includes a casing which is externally threaded to mate with the adapter and a second rod which is threaded to mate with the actuator rod. The hydrant is assembled by removing the lock nut and screwing the parts together while an operating screw is swung free, then swinging the operating screw into engagement with the second rod. A preferred embodiment permits water samples to be taken from the hydrant.
