TEXAS WATER WELL PUMP INSTALLER LICENSE
EXAMINATION COMPLETE QUESTIONS AND DETAILED
SOLUTIONS LATEST UPDATE THIS YEAR JUST RELEASED
Question 1
Which responsibility is considered one of the most important legal duties of a licensed
Texas water well pump installer when installing pumping equipment on a newly
completed potable water well?
A. Installing equipment without following state standards whenever requested by the
property owner
B. Following applicable Texas laws, administrative rules, and accepted installation
standards that protect groundwater quality and public health
C. Allowing unlicensed individuals to complete all electrical work without supervision
D. Ignoring manufacturer installation instructions whenever local conditions differ
Answer: B
Rationale: Texas regulations require licensed installers to follow state laws,
administrative rules, and accepted industry standards to protect groundwater
resources, ensure public safety, and maintain reliable system performance.
Question 2
Before beginning installation of a submersible well pump, which action should always be
completed first to minimize hazards and ensure compliance with accepted safety
practices?
A. Energize the electrical circuit
,B. Disconnect electrical power and verify that all circuits are de-energized
C. Increase pressure tank air pressure
D. Remove the pressure switch cover while power remains on
Answer: B
Rationale: Locking out electrical power before beginning work prevents electrical shock,
accidental motor starts, and serious injuries.
Question 3
Which type of pump is generally considered the most suitable choice for deep water
wells requiring water to be lifted from significant depths?
A. Jet pump
B. Centrifugal surface pump
C. Submersible pump
D. Booster pump
Answer: C
Rationale: Submersible pumps operate below the water level, allowing efficient lifting
from deep wells while reducing suction limitations.
Question 4
Why is proper well sanitation during pump installation considered an essential
requirement for protecting drinking water quality and public health?
A. It improves electrical efficiency only
B. It prevents contaminants, bacteria, and foreign materials from entering the well
during installation
C. It reduces motor voltage
,D. It eliminates the need for pressure tanks
Answer: B
Rationale: Proper sanitation prevents contamination that could affect water quality and
public health.
Question 5
Which component automatically starts and stops a residential well pump according to
system water pressure during normal operating conditions?
A. Check valve
B. Pressure switch
C. Pitless adapter
D. Flow restrictor
Answer: B
Rationale: A pressure switch senses system pressure and controls motor operation
between cut-in and cut-out settings.
Question 6
What is the primary purpose of installing a check valve within an appropriate water well
pumping system?
A. Increase voltage
B. Prevent reverse water flow after the pump stops operating
C. Increase pump horsepower
D. Reduce well depth
Answer: B
, Rationale: Check valves prevent water from flowing backward into the well, maintaining
pressure and protecting equipment.
Question 7
When selecting an appropriate well pump for installation, which combination of
information is generally the most important for achieving satisfactory system
performance?
A. Pump colour and manufacturer logo
B. Well depth, pumping level, required flow rate, and total dynamic head
C. Customer's favourite brand only
D. Pipe colour and pressure switch size
Answer: B
Rationale: Proper sizing requires evaluating water demand, pumping level, and total
dynamic head.
Question 8
Which electrical safety practice should always be followed before removing a pump
control box cover for inspection or maintenance?
A. Touch exposed wires first
B. Verify power has been disconnected and confirm absence of voltage
C. Stand in water while testing
D. Remove grounding conductor
Answer: B
Rationale: Always verify circuits are de-energized before opening electrical equipment.
