given point under normal distribution system conditions measured at the residual
hydrant with no hydrants flowing.
Check Valve ---------CORRECT ANSWER-----------------A valve that allows flow in one
direction but prevents flow in the opposite direction.
Indicating Valve ---------CORRECT ANSWER-----------------A valve that has
components that show if the valve is open or closed. Examples are outside screw
and yoke (OS&Y) gate valves and underground gate valves with indicator posts.

hydrant when it is not in use. These hydrants are used in areas where freezing
may occur.
Flow Hydrant ---------CORRECT ANSWER-----------------The hydrant that is used for
the flow and flow measurement of water during a flow test.
Private Fire Hydrant ---------CORRECT ANSWER-----------------A valved connection on
