Texas Water Well Pump Installer License Examination
,Question 1
Which factor is most important when selecting a submersible pump for a new
water well installation?
A. Paint color of the pump housing
B. Total dynamic head and required flow rate
C. Manufacturer advertising budget
D. Length of electrical conduit only
Answer: B
Rationale: Pump selection primarily depends on required flow rate and total
dynamic head to ensure efficient operation.
Question 2
Why must electrical power always be disconnected before servicing a well pump
installation?
A. To reduce groundwater temperature
B. To prevent electrical shock and accidental motor startup
C. To improve pump efficiency
D. To reduce pipe friction losses
Answer: B
Rationale: Disconnecting power prevents serious injuries from electric shock or
unexpected equipment operation.
Question 3
,Which water system component primarily stores pressurized water and reduces
frequent pump cycling?
A. Check valve
B. Pressure tank
C. Pitless adapter
D. Drop pipe
Answer: B
Rationale: Pressure tanks store water under pressure, reducing excessive pump
starts and extending equipment life.
Question 4
What is the primary purpose of installing a check valve within a water well
pumping system?
A. Increase voltage
B. Prevent reverse water flow
C. Lower groundwater level
D. Increase pipe diameter
Answer: B
Rationale: Check valves prevent water from flowing backward after pump
shutdown.
Question 5
, Which groundwater formation generally provides the highest sustained water
production for properly constructed wells?
A. Solid granite
B. Productive aquifer
C. Clay layer
D. Surface soil
Answer: B
Rationale: Aquifers store and transmit groundwater efficiently, making them
suitable water sources.
Question 6
What is the primary purpose of a pitless adapter in modern water well
installations?
A. Increase pump voltage
B. Provide frost-proof underground water discharge
C. Improve motor horsepower
D. Reduce casing diameter
Answer: B
Rationale: Pitless adapters allow sanitary, frost-resistant underground water
connections.
Question 7
Why is proper grounding essential for electrically powered well pump systems?
