1.
What is the primary purpose of a submersible well pump?
A. To increase well diameter
B. To remove sediment from the well
C. To lift groundwater from the well and deliver it to the
water system
D. To disinfect the well
Correct Answer: To lift groundwater from the well and
deliver it to the water system
Rationale: A submersible pump is installed below the
water level and uses an electric motor and impellers to
move groundwater through the discharge piping into
the pressure system.
2.
Under Arkansas water-well rules, pump installation must be
performed by whom?
A. Any licensed plumber
B. A licensed water well contractor and registered pump
installer
C. Any electrician
D. Any property owner
,Correct Answer: A licensed water well contractor and
registered pump installer
Rationale: Arkansas rules specifically require pump
installation to be performed by a licensed water well
contractor and registered pump installer.
3.
Which Arkansas water well contractor category includes
contracting for installation and repair of pumps and related
equipment but does not include excavating the well?
A. Drilling
B. Pump systems
C. Master plumber
D. Water treatment
Correct Answer: Pump systems
Rationale: The Pump Systems category covers pump
installation and repair and related equipment without
authorizing excavation of the well.
4.
What is the main purpose of a check valve in a submersible
pump system?
A. Increase motor horsepower
B. Reduce wire resistance
C. Prevent water from flowing backward when the pump
stops
D. Increase well yield
Correct Answer: Prevent water from flowing backward
when the pump stops
Rationale: A check valve maintains the water column
and helps prevent reverse flow through the pump and
excessive cycling or water hammer.
5.
,Pump capacity should be consistent with the well's:
A. Casing color
B. Property value
C. Intended use and yield characteristics
D. Electrical meter size only
Correct Answer: Intended use and yield characteristics
Rationale: Arkansas requirements state that pump
capacity must be appropriate for the intended
groundwater use and the yield characteristics of the
well.
6.
What is pump head?
A. The physical height of the pump motor
B. The pressure or energy required to move water
through the system
C. The diameter of the well casing
D. The depth of the electrical conduit
Correct Answer: The pressure or energy required to
move water through the system
Rationale: Pump head represents the energy per unit
weight of water needed to overcome elevation,
pressure, friction, and other system losses.
7.
Approximately how many feet of water column correspond to 1
psi?
A. 1.00 ft
B. 0.433 ft
C. 2.31 ft
D. 10.00 ft
Correct Answer: 2.31 ft
, Rationale: One psi is approximately equal to 2.31 feet of
water. This conversion is commonly used in pump
calculations.
8.
Approximately how many psi are represented by 100 feet of
water head?
A. 2.31 psi
B. 10 psi
C. 43.3 psi
D. 231 psi
Correct Answer: 43.3 psi
Rationale: Pressure in psi can be calculated by dividing
feet of water by 2.31. Thus, 100 ÷ 2.31 is approximately
43.3 psi.
9.
What does TDH stand for?
A. Total Discharge Height
B. Total Dynamic Head
C. Tank Delivery Height
D. Terminal Drive Horsepower
Correct Answer: Total Dynamic Head
Rationale: Total Dynamic Head is the total head the
pump must overcome while operating, including static
elevation, pressure requirements, and friction losses.
10.
Which factor normally increases friction loss in a water-piping
system?
A. Increasing pipe diameter
B. Reducing flow rate
C. Increasing flow rate
D. Removing fittings
