Question 1
Which component is primarily used to maintain pressure in a
typical residential water system?
A. Check valve
B. Pressure tank
C. Foot valve
D. Flow meter
Answer: B. Pressure tank
Rationale: A pressure tank stores pressurized water and reduces
the frequency with which the pump must start and stop, helping
maintain relatively stable system pressure.
Question 2
What is the primary purpose of a pressure switch in a water well
system?
A. To measure water quality
B. To regulate pump starting and stopping
,C. To increase well yield
D. To filter sediment
Answer: B. To regulate pump starting and stopping
Rationale: The pressure switch responds to system pressure and
signals the pump to start or stop at predetermined pressure
settings.
Question 3
Which condition is most likely to cause a submersible pump to
run continuously without reaching the pressure shutoff point?
A. Excessive system demand or insufficient pump capacity
B. A fully charged pressure tank
C. A properly adjusted pressure switch
D. A closed electrical disconnect
Answer: A. Excessive system demand or insufficient pump
capacity
Rationale: If demand exceeds the pump's ability to produce the
required flow and pressure, the system may never reach the
pressure-switch cut-out setting.
Question 4
What does GPM commonly represent in water-system
calculations?
,A. Gallons per meter
B. Gallons per minute
C. Gallons per mile
D. Ground pressure measurement
Answer: B. Gallons per minute
Rationale: GPM is the standard abbreviation for gallons per
minute and is commonly used to express water flow rate.
Question 5
Which factor is most important when selecting a well pump?
A. The color of the well casing
B. Required flow and total dynamic head
C. The age of the property
D. The size of the electrical service alone
Answer: B. Required flow and total dynamic head
Rationale: Pump selection must account for the required flow
rate and the total head against which the pump must operate,
including elevation, pressure requirements, and friction losses.
Question 6
What is static water level?
A. Water level while the pump is operating
B. Water level in the well when the system is not pumping
, C. Maximum pump discharge pressure
D. Depth of the well casing
Answer: B. Water level in the well when the system is not
pumping
Rationale: Static water level is measured when the well is at rest
and is not being influenced by pumping.
Question 7
What is drawdown?
A. The increase in static water level
B. The difference between static and pumping water levels
C. The total depth of the well
D. The pressure in a storage tank
Answer: B. The difference between static and pumping water
levels
Rationale: Drawdown is the decline in water level caused by
pumping and is calculated from the difference between static
and pumping levels.
Question 8
Which device helps prevent reverse flow in a water system?
A. Check valve
B. Pressure gauge
