1. The pressure that exists in the distribution system, Residual Pressure
measured at the residual hydrant at the time the flow
readings are taken at the flow hydrants.
2. The pressure that exists at a given point under normal Static Pressure
distribution system conditions measured at the resid-
ual hydrant with no hydrants flowing.
3. A valve that allows flow in one direction but prevents Check Valve
flow in the opposite direction.
4. A valve that has components that show if the valve is Indicating Valve
open or closed. Examples are outside screw and yoke
(OS&Y) gate valves and underground gate valves with
indicator posts.
5. Fire hydrant that has its operating valve located at the Dry-Barrel Hydrant
base or foot of the hydrant rather than in the barrel
of the hydrant. When operating properly, there is no
water in the barrel of the hydrant when it is not in use.
These hydrants are used in areas where freezing may
occur.
6. The hydrant that is used for the flow and flow mea- Flow Hydrant
surement of water during a flow test.
7. A valved connection on a water supply system having Private Fire Hydrant
one or more outlets that is used to supply hose and
fire department pumpers with water on private prop-
erty.
8. Public Hydrant

A valved connection on a water supply system having
one or more outlets that is used to supply hose and
fire department pumpers with water.
9. The hydrant that is used for measuring static and Residual Hydrant
residual pressures during a flow test.
10. A hydrant used in areas that are NOT susceptible to Wet-Barrel Hydrant
freezing. The barrel of the hydrant is normally filled
with water.
11. ________________hydraulic calculations shall show that Private fire service main's
the main is able to supply the total demand at the
appropriate pressure.
12. Tanks shall be installed in accordance with. NFPA 22
13. The connection from the hydrant to the main shall not 6 in
be less than_____.
14. Where post indicator valves are used, they shall be set 32-40 in
so that the top of each post is____________ above the
final grade.
15. Hydrants shall be located not less than _______ from 40 ft
the building being protected.
16. Where hydrants located closer than 40ft to the build- AHJ (authority having juris-
ing, shall be permitted to be used where approved by diction)
the_____.
17. The center of a hose outlet located in a hose house 18 in
shall not be less than _______ above the final grade.
