TM 10-4320-303-132.12.2 FailureofBoostPumpingStation .(Continued)f. Boost pumps (operating in electric/automatic mode) should decrease to idle automatically. Operatorsat boost pumping stations should make certain their units have adjusted properly. Operators mustalso monitor readings on pressure gages. Reference the applicable technical manual andimmediately shut down 600 GPM pumping assemblies that fail to remain primed.g. Close gate valves connected to storage assemblies.h. Distribution points continue to operate as long as enough water remains in storage tanks. When waterin storage tanks drops to inoperable level, shut down operation of distribution points (para 2.5.5).Refer to the applicable technical manual and shut down engine on 125 GPM pumping assembly (para2.5.5.2).2.12.3 FailureofStorageAssembly.If storage assembly fails, operation is possible ONLY under thefollowing conditions:(1) Two storage assemblies are in use, and(2) The unaffected storage assembly is being used with a distribution point. To temporarily adaptoperation, proceed as follows:a. Notify operators at other stations of equipment failure. 600 GPM pumping assemblies may requireadjustment, if necessary refer to applicable technical manual and adjust operation of 600 GPMpumping assemblies accordingly.b. Close gate valve connected to defective storage tank (para 2.5.4).c. If distribution point is being used with defective storage tank, shut down distribution point (para 2.5.5).Refer to the applicable technical manual and shut down engine on 125 GPM pumping assembly.2.12.4 FailureofDistributionPoint .If a distribution point fails, TWDS operation is possible ONLY if twodistribution points are in use. To temporarily adapt TWDS operation, proceed as follows:a. Notify operators at other stations of equipment failure. 600 GPM pumping assemblies may requireadjustment, if necessary refer to the applicable technical manual and adjust operation of 600 GPMpumping assemblies accordingly.b. Close gate valve connected to 20,000 gallon pillow tank in use with defective distribution point (para2.5.5).c. Shut down operation of defective distribution point (para 2.5.5). Refer to the applicable technicalmanual and shut down engine on 125 GPM pumping assembly (2.5.5.2).2-116
