TM 10-4320-346-12&P Table 3-1. Operator Troubleshooting. MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION Step 5. Valve assembly on collapsible water drum coupler valve assembly is defective. Refer to troubleshooting section of collapsible water drum technical manual. 4. WATER CONTINUES TO FLOW WHEN ALL VALVES ARE CLOSED. Step 1. Test for defective ball valve assembly by disconnecting hose assembly nearest to outlet of ball valve assembly, closing ball valve, and then checking ball valve outlet for water leakage. If water leakage is found, ball valve assembly is defective and unit maintenance must be notified. Step 2. Test for defective nozzle assembly by starting FAWPSS pump and engine assembly and then opening and closing nozzle valve assembly. Check for continued water leakage from nozzle spout when nozzle is closed. If water continues to leak from nozzle spout when nozzle assembly is closed, nozzle assembly is defective and unit maintenance must be notified. 5. HOSE ASSEMBLY LEAKS. Step 1. Gaskets are missing from hose connection joints. Remove affected hose from connection and check that gasket is properly placed within the coupling half. If gasket is missing, contact unit maintenance for a replacement gasket. Step 2. Cam-lock couplings are improperly fastened. Disconnect couplings from hose and then reconnect couplings. Be sure that the coupling cam-locking mechanism is properly positioned to seal the hose joint. Step 3. Dust or dirt is trapped inside the hose coupling connection. Disconnect couplings from hose and check for dust or dirt inside couplings. Remove any dust or dirt found and reconnect hose assembly. 3-3
