TM 10-4320-345-13
2-21. EMERGENCY PROCEDURES-cont.
(8) Connect lead pumping station components to 600 gpm pump (para 2-11f).
(9) Open valves L1 and L2.
(10) Fill hoseline (para 2-13b).
(11) Startup water system (para 2-13c).
b.
Boost Pumping Station Failure Refer to figure 2-30.
(1) Shutdown defective 600 gpm pump. Refer to the applicable TM.
(2) Open valve B1, and close valves 1B2 and B3 to bypass defective 600 gpm pump.
NOTE
Opening valve BI allows water to bypass the 600 gpm pump. System operation may continue
while defective boost pump is being replaced.
(3) Disconnect boost pumping station components from 600 gpm pump (para 2-16h).
(4) Remove defective 600 gpm pump from boost pumping station.
(5) Position spare 600 gpm pump in boost pumping station.
(6) Connect boost pumping station components to 600 gpm pump (para 2-11g).
(7) Connect hose to suction port on 600 gpm pump.
(8) Open gate valves B2 and B3, and close gate valve BI.
(9) Start and operate 600 gpm pump Refer to the applicable TM.
c.
Component Failure. Refer to figure 2-30 In the event of a hose, coupling, tank or valve rupture, the
failed component must be isolated as soon as possible to stop the loss of water.
CAUTION
To prevent damage to the equipment, water system must be shut down if isolating the failed
component(s) will block water flow to or from the 600 gpm pumps.
(1) If failure occurs in main hoseline, shutdown lead and boost pumping stations (para 2-13d).
(2) Close nearest upstream and downstream control valves to stop water flow through failed
component.
