A fire hydrant system includes a fire hydrant (upper barrel and bonnet) that is separate from a first cover tube and a second cover tube that house a valve stem. To activate the system, a user opens a gate valve via the valve stem, thereby allowing water to enter the upper barrel of the fire hydrant. When the gate valve is closed, a drain valve allows water to exit the upper barrel, lower barrel, and shoe fitting, preventing damage during freezing temperatures.

The present invention relates to a connector (100) for a water system. The connector comprises an inlet connector (105), a connector body and an outlet connector (120) arranged in sequence. The connector body is open-sided so as to form a tundish having an open air gap between the inlet and outlet connectors (105, 120), through which water can fall in use. The connector (100) further comprises a sensor for detecting the presence of water within the connector body.

A device for monitoring manual flushing of a hydrant includes an adapter attached to a flushing hose and attachable to an outlet of a water hydrant, an access port on the adapter, the access port being sized to take a sample of a stream of water flowing through the adapter, a flexible hose attached to the access port, an analyzer box containing a sensor adapted to sense a characteristic of water, the sensor being operatively connected to the flexible hose, and an alarm operatively attached to the sensor.

A hydrant apparatus may be employed to monitor a water distribution system, and may include a sensor, a processor, and a local clock source. The apparatus may wake from a low power mode to a sensing mode, receive the sensor data, associate the sensor data with a first local clock time, and return the apparatus to the low power mode from the sensing mode. The apparatus may subsequently wake to an operational mode, determine a second local clock time subsequent to the first local clock time, associate an external clock time with the second local clock time, determine an offset for the received sensor data based on the first local clock time and the association between the second local clock time and the external clock time, and transmit the sensor data and the offset to an external monitoring system.

A sanitary hydrant comprises an isolated reservoir that can be positioned below a freeze level at the location of installation. A piston within the isolated reservoir is operable to expel, during a downward stroke, stored fluid from the reservoir before actuating a valve that allows fluid to flow from a fluid supply source through the hydrant. On an upward stroke, the piston releases the valve and generates a negative pressure within the reservoir that draws fluid from within the hydrant into the reservoir.

An embodiment of a fluid valve includes a substantially flat face plate, a receptacle, a cavity, and a valve assembly. The receptacle is disposed in the face plate and has at least one protrusion each configured to engage a respective at least one groove of a valve-opening-and-fluid-dispensing device. The cavity has a front end in fluid communication with the receptacle, and has a rear end. And the valve assembly is disposed in the cavity, includes a first sealing ring, is configured to form a seal by urging the sealing ring against the rear end of the cavity in response to the valve-opening-and-fluid-dispensing device being absent from the receptacle, and is configured to allow fluid to flow into the rear end of the cavity in response to the valve-opening-and-fluid-dispensing device being disposed in the receptacle.
