The regulatory portions below are aligned to the Texas Department of Licensing and
Regulation's Water Well Drillers and Pump Installers program, including Texas
Occupations Code Chapter 1902 and 16 TAC Chapter 76. TDLR identifies the TX
General Pump Installer as a pump-installer endorsement examination.
,Question 1
A. Install any pump because pump installation is not separately regulated.
B. Obtain the appropriate pump installer authorization before performing
regulated pump installation work.
C. Obtain only a public water-system operator license.
D. Obtain a water-well driller license regardless of the pump work.
🔴 Correct Answer: B. Obtain the appropriate pump installer authorization
before performing regulated pump installation work.
🔵 Explanation: Texas separately regulates water-well pump installation. TDLR
administers the pump-installer program under Texas Occupations Code Chapter
1902 and 16 TAC Chapter 76.
Question 2
A licensed installer is asked to install a pump outside the endorsement category
for which the installer is qualified. What is the most appropriate response?
A. Perform the installation because all pump work is equivalent.
B. Perform the installation if the customer signs a waiver.
C. Decline or obtain the appropriate qualification before performing the regulated
work.
D. Perform the installation if another employee observes it.
🔴 Correct Answer: C. Decline or obtain the appropriate qualification before
performing the regulated work.
🔵 Explanation: A licensee should not perform or offer services beyond the scope for
which the licensee is properly qualified. Competency and authorization must match
the work being undertaken.
Question 3
Which agency has primary jurisdiction over Texas private water-well pump
installation licensing?
A. Texas Commission on Environmental Quality
B. Texas Department of Licensing and Regulation
C. Texas Department of State Health Services
D. Texas Water Development Board
🔴 Correct Answer: B. Texas Department of Licensing and Regulation.
🔵 Explanation: TDLR regulates private water-well drilling and pump installation.
TCEQ has separate jurisdiction over public-water-supply matters.
,Question 4
A contractor proposes allowing an unlicensed worker to independently perform
pump installation while the licensed installer remains available by telephone.
Which conclusion is most appropriate?
A. The arrangement is acceptable if the worker has five years of experience.
B. The arrangement is acceptable if the customer approves.
C. The arrangement does not satisfy required supervision conditions.
D. The arrangement is acceptable if the installation is residential.
🔴 Correct Answer: C. The arrangement does not satisfy required supervision
conditions.
🔵 Explanation: TDLR guidance requires appropriate direct supervision and, for an
unlicensed assistant performing installation operations, the license holder must be
present at the well site.
Question 5
An installer discovers that a proposed pump installation could create
communication between two water-producing zones. What should be prioritized?
A. Increasing pump horsepower
B. Preventing unwanted commingling through proper well completion
C. Increasing pressure-switch differential
D. Installing a larger pressure tank
🔴 Correct Answer: B. Preventing unwanted commingling through proper well
completion.
🔵 Explanation: Hydraulic isolation of producing zones is a well-integrity and water-
quality issue. Pump capacity cannot compensate for improper completion.
Question 6
A pump produces adequate pressure at the wellhead but insufficient pressure at a
remote fixture. Which diagnostic step is most useful initially?
A. Replace the pump motor immediately.
B. Determine whether excessive friction loss or inadequate pipe sizing exists
downstream.
C. Increase motor voltage.
D. Reduce the pressure-tank size.
🔴 Correct Answer: B. Determine whether excessive friction loss or inadequate
pipe sizing exists downstream.
🔵 Explanation: A significant pressure difference between the pump discharge and
, point of use can result from elevation, friction, restrictions, undersized piping, or
control components.
Question 7
A pump's required total dynamic head increases while flow demand remains
constant. What generally happens to the operating point?
A. It moves toward a higher-flow condition.
B. It moves toward a lower-flow condition.
C. Flow is unaffected under all conditions.
D. Motor speed automatically doubles.
🔴 Correct Answer: B. It moves toward a lower-flow condition.
🔵 Explanation: The operating point is established by the intersection of pump
performance and system curves. Increasing system head generally reduces the
resulting flow.
Question 8
A pump curve shows that the selected pump cannot provide the required flow at
the calculated total dynamic head. What is the technically appropriate action?
A. Assume the published curve is optional.
B. Select a pump whose operating range satisfies the duty point.
C. Increase the pressure-switch setting indefinitely.
D. Reduce pipe diameter to increase pressure.
🔴 Correct Answer: B. Select a pump whose operating range satisfies the duty
point.
🔵 Explanation: Pump selection must be based on the required flow and total
dynamic head rather than horsepower alone.
Question 9
Which factor most directly contributes to total dynamic head?
A. Only static water level
B. Static lift, pressure requirements, and friction/minor losses
C. Motor frame size only
D. Wire insulation temperature
🔴 Correct Answer: B. Static lift, pressure requirements, and friction/minor
losses.
🔵 Explanation: Total dynamic head incorporates the elevation component and the
