hydrant with no hydrants flowing.
A valve that allows flow in one direction but prevents flow in
Indicating Valve
the opposite direction.
A valve that has components that show if the valve is open or
closed. Examples are outside screw and yoke (OS&Y) gate Dry-Barrel Hydrant
valves and underground gate valves with indicator posts.

foot of the hydrant rather than in the barrel of the hydrant.
When operating properly, there is no water in the barrel of the Flow Hydrant
hydrant when it is not in use. These hydrants are used in areas
where freezing may occur.
The hydrant that is used for the flow and flow measurement
Private Fire Hydrant
of water during a flow test.
