Texas Water Well Pump Installer License Examination
1. Which primary consideration should a licensed pump installer evaluate
before selecting equipment for a private water well system?
A. The color of the well casing
B. The required flow rate and total dynamic head
,C. The homeowner's preferred pump brand
D. The distance between nearby trees
Correct Answer: B. The required flow rate and total dynamic head
Rationale: Pump selection depends heavily on the required flow and total
dynamic head. Choosing equipment without evaluating these factors can result in
inadequate pressure, poor performance, or excessive energy consumption.
2. When installing a submersible pump in a water well, why should the installer
carefully determine its proper setting depth?
A. To improve the appearance of the wellhead
B. To ensure adequate water supply while preventing damage from excessive
drawdown
C. To eliminate the need for electrical grounding
D. To increase the pressure tank's air volume
Correct Answer: B. To ensure adequate water supply while preventing damage
from excessive drawdown
Rationale: Proper pump depth helps keep the pump adequately submerged
during operation while avoiding excessive drawdown that could expose the pump
or cause overheating and operational problems.
3. What is the primary purpose of a pressure tank installed in a typical
residential private water well pumping system?
A. To permanently increase the well's natural yield
B. To reduce pump cycling and provide stored pressurized water
C. To replace all electrical motor controls
D. To prevent the well casing from corroding
Correct Answer: B. To reduce pump cycling and provide stored pressurized
water
,Rationale: A properly sized pressure tank provides water between pump cycles
and reduces frequent starting and stopping, which can significantly extend pump
and motor life.
4. Why is a check valve commonly installed in a water well pumping system
using a submersible pump?
A. To increase the electrical voltage supplied to the motor
B. To prevent pressurized water from flowing backward toward the well
C. To disinfect the water automatically
D. To eliminate the requirement for pressure controls
Correct Answer: B. To prevent pressurized water from flowing backward toward
the well
Rationale: A check valve maintains system pressure and prevents reverse flow
when the pump stops. Proper placement and installation are essential for reliable
operation.
5. Before working on electrical components associated with a well pump, what
safety procedure should generally be completed first?
A. Increase the pressure switch setting
B. Disconnect and verify isolation of the electrical power supply
C. Open every household faucet
D. Remove the well casing
Correct Answer: B. Disconnect and verify isolation of the electrical power supply
Rationale: Electrical power must be disconnected and the circuit verified de-
energized before servicing equipment. This reduces the risk of electrical shock, arc
flash, and accidental motor operation.
, 6. What condition can occur when a pump is selected with insufficient capacity
to meet the required system flow and pressure demands?
A. The system may fail to deliver adequate water service
B. The well casing automatically becomes larger
C. The pressure tank becomes unnecessary
D. Electrical grounding becomes optional
Correct Answer: A. The system may fail to deliver adequate water service
Rationale: An undersized pump may not produce the required flow at the
necessary pressure. Proper hydraulic calculations should be completed before
selecting pumping equipment.
7. Why should a pump installer consider the static water level and pumping
water level when determining proper pump installation?
A. These measurements help determine available water depth and potential
drawdown conditions
B. They determine the paint color required for the wellhouse
C. They eliminate the need for flow testing
D. They establish the homeowner's electrical service size automatically
Correct Answer: A. These measurements help determine available water depth
and potential drawdown conditions
Rationale: Static and pumping water levels provide important information about
the aquifer and well performance. The difference between them indicates
drawdown during pumping.
8. What is the primary function of a pressure switch in a conventional water
well pressure system?
A. It controls pump operation based on system pressure
B. It filters sediment from groundwater
