QUESTIONS AND SOLUTIONS RATED A+
✔✔Automatic Drain Valve (Automatic Drip or Ball Drip) - ✔✔A device intended to
remove water using gravity from piping or valve cavities, which is required to be empty
when the system is not discharging water.
✔✔Control Valve (Shutoff Valve) - ✔✔A valve controlling flow to water-based fire
protection systems and devices
✔✔Corrosion-Resistant Piping - ✔✔Piping that has the property of being able to
withstand deterioration of its surface or its properties when exposed to its environment
✔✔Corrosion-Retarding Material - ✔✔A lining or coating material that when applied to
piping or appurtenances has the property of reducing or slowing the deterioration of the
object's surface or properties when exposed to its environment
✔✔Fire Department Connection - ✔✔A connection through which the fire department
can pump supplemental water into the sprinkler system, standpipe, or other water-
based fire protection systems, thereby supplementing existing water supplies.
✔✔Fire Pump - ✔✔A pump that is a provider of liquid flow and pressure dedicated to
fire protection.
✔✔Hose House - ✔✔An enclosure located over or adjacent to a hydrant or other water
supply designed to contain the necessary hose nozzles, hose wrenches, gaskets, and
spanners to be used in fire fighting in conjunction with and to provide aid to the local fire
department
✔✔Hydrant Butt - ✔✔The hose connection outlet of a hydrant
✔✔Hydraulically Calculated Water Demand Flow Rate - ✔✔The water flow rate for a
system or hose stream that has been calculated using accepted engineering practices
✔✔Private Fire Service Main - ✔✔Private fire service main, as used in this standard, is
that pipe and its appurtenances on private property (1) between a source of water and
the base of the system riser for water-based fire protection systems, (2) between a
source of water and inlets to foam-making systems, (3) between a source of water and
the base elbow of private hydrants or monitor nozzles, and (4) used as fire pump
suction and discharge piping, (5) beginning at the inlet side of the check valve on a
gravity or pressure tank
✔✔Pumper Outlet - ✔✔The hydrant outlet intended to be connected to a fire
department pumper for use in taking supply from the hydrant.
, ✔✔Rated Capacity - ✔✔The flow, either measured or calculated, that is available from a
hydrant at the designated residual pressure (rated pressure)
✔✔System Working Pressure - ✔✔The maximum anticipated static (nonflowing) or
flowing pressure applied to fire protection system components exclusive of surge
pressures and exclusive of pressure from the fire department connection
✔✔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 flow rates intended 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 attached
appurtenances consisting of subjecting the piping to an increased internal pressure for a
specified period of duration to verify system integrity and leak rates
✔✔An acceptable water supply source - ✔✔A connection to a reliable waterworks
system shall be________________________________________________
✔✔Hydraulic Calculations - ✔✔____________________________ shall show that the
main is able to supply the total flow rate at the required design pressure
✔✔6 in - ✔✔(Private Fire Service Mains) For mains that supply fire hydrants, pipe size
shall not be less than _______________
✔✔1.) Check Valves
2.) Detector Check Valves
3.) Backflow prevention valves
4.) Other similar appurtenances - ✔✔The following shall not be installed between a fire
hydrant and the control valve for that hydrant:
✔✔Master Streams - ✔✔_______________________ shall be delivered by monitor
nozzles, hydrant-mounted monitor nozzles, and other ___________________
equipment capable of delivering more than 250 gpm (950 L/min)
✔✔Master Streams - ✔✔_________________________ shall be provided as protection
for the following:
1.) Large amounts of combustible materials located in yards
2.) Large amounts of combustible materials in inaccessible locations.
3.) Occupancies presenting special hazards, as required by the AHJ.
