MWS CCRE UPDATED Exam Questions
and CORRECT Answers
Identify two correct statements about conducting a daily inspection of an MWS apparatus
equipped with a fire pump - CORRECT ANSWER - Confirm that the foam tank level is
full.
Operate the pump drive control.
Most jurisdictions prefer to draft from a static water source during service testing because it: -
CORRECT ANSWER - Is a true test of the pump's ability.
Place the steps for part 2 of the pressure control test in the correct order - CORRECT
ANSWER - 1. Set the fire pump so that it is discharging at a net pump discharge pressure
of 150 psi
2. Reduce the pumping engine throttle until the net pump discharge pressure drops to 90 psi
3. Set the pressure control device to maintain the discharge pressure at 90 psi.
4. Close the flowing valves one at a time.
5. The pump discharge pressure should rise no more than 30 psi when all valves are closed.
Match each type of MWS apparatus record to the element or activity that is being inspected -
CORRECT ANSWER - Oil filter— fuel, oil and mileage record
Pump valves— daily inspection
Safety inspection record— weekly inspection
Pump and intake strainers— weekly inspection
When conducting a service test using a static water source you must have ______ feet of hard
suction hose for drafting - CORRECT ANSWER - 20
, All of the following are important for maintaining inspection documentation of an MWS
apparatus except - CORRECT ANSWER - Verifying that you are inspection the correct
apparatus
The purpose of the priming device test is to - CORRECT ANSWER - Evaluate how
quickly the priming device can create a vacuum to bring water through a pump to the discharge
hose.

column of mercury of at least: - CORRECT ANSWER - 22 inches
Testing the discharge pressure gauge begins by: - CORRECT ANSWER - Disconnecting
all preconnected hoselines and screwing all caps onto their discharges.
