500 - -pumps other than those specified in this standard and having
different design features shall be permitted to be installed where such
pumps are listed by a testing laboratory. these pumps shall be limited to

- true - -Any source of water that is adequate in quality, quantity, and
pressure shall be permitted to provide the supply for a fire pump.
- 100 - -Where maximum flow available from the water supply cannot
provide a flow of 150 percent of the rated flow of the pump , but the water
supply can provide the greater of _____ percent of rated flow or the
maximum flow demand of the fire protection systems, the water supply shall
be deemed to be adequate. in this case, the maximum flow shall be
considered the highest flow that the water supply cannot achieve.

material value without the pump, the pump shall be installed with a ______.
- OS&Y - -A listed ______ gate valve shall be installed in the suction pipe. No
other kind of valves shall be installed in the suction piping within 50' of the
fire pump.

same size, they shall be connected with an _______ tapered reducer or
increase installed in such a way as to avoid air pockets.
- Double intake screens - -Where the water supply is obtained from an open
source such as a pond or wet pit, the passage of materials that might clog
the pump shall be obstructed. ____________ shall be provided at the suction
intake. Screens shall be removable or an situ cleaning shall be provided.
- check valve - -A listed ______ or backflow preventer shall be installed in the
pump discharge assembly.
- Butterfly - -Where pumps are installed in a series, a __________ valve shall
not be installed between pumps.
- check valve - -When a low suction throttling valve is used, it shall be
installed according to manufacturers reccomendations in the piping between
the pump and the discharge _________.
- 1" - -in fire pump assemblies a clearance of not less than _______ shall be
provided around pipes that pass through walls or floors.
- pressure relief valve - -Where a diesel engine fire pump is installed and
where a total of 121 percent of the net rated shutoff (churn) pressure plus
the maximum static suction pressure, adjusted for elevation, exceeds the
pressure for which the system components are rated, a ________ shall be
installed.
- check valve - -The relief valve shall be located between the pump and the
pump discharge _________ and shall be so attached that it can be readily
removed for repairs without disturbing the piping.
