,Page 2 of 102
1. Which organization is responsible for regulating pump installers and issuing licenses for
water well pump installation work in Texas?
A. Texas Water Development Board
B. Texas Commission on Environmental Quality
C. Texas Department of Licensing and Regulation
D. Texas Department of Agriculture
Correct Answer: C
Rationale: Pump installers are licensed and regulated by the Texas Department of Licensing and
Regulation, which oversees compliance with installation standards and professional licensing
requirements.
2. When determining the proper pump size for a water well installation, which measurement
is most important for calculating total dynamic head?
A. Distance between the well and electrical panel
B. Static water level and pumping water level
C. Diameter of the pressure tank
D. Type of pressure switch used
Correct Answer: B
,Page 3 of 102
Rationale: Total dynamic head includes static water level, pumping level, and friction losses in
piping.
3. Which pump type is most commonly installed in deep wells because the entire pump unit
operates underwater in the well casing?
A. Centrifugal pump
B. Submersible pump
C. Booster pump
D. Surface jet pump
Correct Answer: B
Rationale: Submersible pumps operate underwater and are commonly used for deep well
systems.
4. What is the primary purpose of a pressure tank in a residential water well pumping system
installation?
A. Increase pump motor horsepower
B. Maintain system pressure and reduce pump cycling
C. Purify groundwater before use
D. Increase well yield
, Page 4 of 102
Correct Answer: B
Rationale: Pressure tanks store water under pressure and prevent frequent pump starts.
5. Which device installed in a pump system prevents water from flowing backward into the
well after the pump stops operating?
A. Pressure switch
B. Check valve
C. Pressure regulator
D. Flow sensor
Correct Answer: B
Rationale: A check valve allows water flow in one direction and prevents backflow.
6. What is the term used to describe the difference between the static water level and the
pumping water level in a well system?
A. Recovery rate
B. Drawdown
C. Pressure drop
D. Dynamic lift
