WEEKLY FIRE PUMP CERTIFICATION EXAM
1. A fire pump being tested for weekly certification must deliver its rated
capacity at what percentage of its rated net pressure?
A) 100%
B) 110%
C) 150%
D) 65%
Correct Answer: A) 100%
Rationale: Weekly certification tests require the pump to meet its rated
capacity at 100% of rated net pressure to verify performance per NFPA
and CAL FIRE standards.
2. Cavitation in a fire pump is most likely to occur when:
A) The discharge valve is fully open
B) Net positive suction head available (NPSHa) is less than net positive
suction head required (NPSHr)
C) The impeller speed is below 50% of rated RPM
D) The packing gland is over-tightened
Correct Answer: B) Net positive suction head available (NPSHa) is
less than net positive suction head required (NPSHr)
Rationale: Cavitation occurs when suction conditions are inadequate,
causing vapor bubbles to form and collapse, damaging the impeller.
,3. During the weekly pump test, the pressure relief valve on a CAL
FIRE fire pump should activate at no more than:
A) 150 psi
B) 200 psi
C) 250 psi
D) 350 psi
Correct Answer: B) 200 psi
Rationale: CAL FIRE specifies system pressure not to exceed 200 psi to
protect hoselines and fittings, with relief valves set accordingly.
4. What is the minimum acceptable flow rate for a 500 gpm rated fire
pump during the weekly certification test?
A) 400 gpm
B) 450 gpm
C) 500 gpm
D) 550 gpm
Correct Answer: C) 500 gpm
Rationale: The pump must achieve its full rated capacity (500 gpm) to
pass the weekly certification test.
5. The weekly test of a fire pump must include running the pump under
load for at least:
A) 5 minutes
B) 10 minutes
C) 15 minutes
D) 30 minutes
Correct Answer: B) 10 minutes
*Rationale: NFPA 25 and CAL FIRE protocols require a 10-minute
continuous run at rated conditions to ensure thermal and mechanical
stability.*
, 6. Which component is most likely to overheat if the pump is operated in
“churn” (no flow) for extended time?
A) Impeller
B) Packing gland
C) Pump casing
D) Relief valve spring
Correct Answer: C) Pump casing
Rationale: Without flow, water inside the casing absorbs all mechanical
energy, causing rapid temperature rise and potential damage.
7. During weekly testing, the pump packing glands should leak at a rate
of approximately:
A) No leakage allowed
B) 1–2 drops per minute
C) 10–20 drops per minute
D) 30–60 drops per minute
Correct Answer: D) 30–60 drops per minute
*Rationale: A slight, steady leak (30–60 drops/min) lubricates and cools
the shaft; zero leak indicates overtightening, excessive leak indicates
worn packing.*
8. The weekly fire pump test must be recorded and retained for a
minimum of:
A) 1 year
B) 3 years
C) 5 years
D) 10 years
Correct Answer: B) 3 years
Rationale: CAL FIRE and NFPA 25 require maintenance and testing
records kept for at least 3 years for audit and trend analysis.
