TFM10 NFPA 24 LATEST 2026 EXAM QUESTIONS AND
SOLUTIONS RATED A+
✔✔Static Pressure - ✔✔The pressure that exists at a given point under normal
distribution system conditions measured at the residual hydrant with no hydrants
flowing.
✔✔Flow Test - ✔✔A test performed by the flow and measurement of water from one
hydrant and the static and residual pressures from an adjacent hydrant for the purpose
of determining the available water supply at that location.
✔✔Flushing Test - ✔✔A test of a piping system using high velocity flows to remove
debris from the piping system prior to it being placed in service
✔✔Hydrostatic Test - ✔✔A test of a closed piping system and its appurtenances
consisting of subjecting to an increased internal pressure for a specified duration to
verify system integrity and system leakage rates.
✔✔Check Valve - ✔✔A valve that allows flow in one direction but prevents flow in the
opposite direction.
✔✔Indicating Valve - ✔✔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.
✔✔Dry-Barrel Hydrant - ✔✔Fire hydrant that has its operating valve located at the 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.
✔✔Flow Hydrant - ✔✔The hydrant that is used for the flow and flow measurement of
water during a flow test.
✔✔Private Fire 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 on
private property.
✔✔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.
✔✔Residual Hydrant - ✔✔The hydrant that is used for measuring static and residual
pressures during a flow test
