A. Texas Commission on Environmental Quality
B. Texas Department of Licensing and Regulation
C. Texas Water Development Board
D. Texas Department of State Health Services
✅ ANSWER : B
Explanation: Pump installers in Texas are regulated by the Texas Department
of Licensing and Regulation (TDLR) under TAC Chapter 65.


2. What is the primary purpose of a pressure tank in a water system?
A. Increase pump horsepower
B. Store water and reduce pump cycling
C. Filter contaminants
D. Increase pipe pressure rating
✅ ANSWER : B
Explanation: Pressure tanks store pressurized water and reduce frequent pump
starts, extending pump life.


3. Which type of pump is best suited for deep wells over 100 feet?
A. Jet pump
B. Centrifugal pump
C. Submersible pump
D. Booster pump
✅ ANSWER : C
Explanation: Submersible pumps push water upward and are efficient for
deep well applications.

,4. What does “Total Dynamic Head (TDH)” include?
A. Static lift only
B. Pipe diameter
C. Static head + friction losses
D. Pump voltage
✅ ANSWER : C
Explanation: TDH is the total resistance the pump must overcome, including
elevation and friction losses.


5. What electrical condition is most dangerous to pump motors?
A. Slight overvoltage
B. Balanced load
C. Low voltage
D. Proper grounding
✅ ANSWER : C
Explanation: Low voltage causes motors to overheat and draw excessive
current.


6. Which device protects a pump from running dry?
A. Pressure switch
B. Check valve
C. Low-water cutoff
D. Gate valve
✅ ANSWER : C
Explanation: A low-water cutoff shuts down the pump if water levels drop too
low.


7. What is the minimum requirement to legally install pumps in Texas?
A. Plumbing license
B. Electrical license
C. Pump Installer license
D. Contractor registration

,✅ ANSWER : C
Explanation: Texas law requires a TDLR-issued Pump Installer license.


8. Which pipe material is commonly used in well drop pipe applications?
A. PVC Schedule 40
B. Copper Type L
C. Galvanized steel
D. ABS
✅ ANSWER : A
Explanation: PVC Schedule 40 or 80 is lightweight, corrosion-resistant, and
commonly used.


9. What does a check valve prevent?
A. Air entry
B. Pressure loss
C. Backflow
D. Electrical surge
✅ ANSWER : C
Explanation: Check valves prevent water from flowing backward into the
pump.


10. What is the function of a pressure switch?
A. Controls water temperature
B. Turns pump on/off based on pressure
C. Measures flow rate
D. Filters debris
✅ ANSWER : B
Explanation: Pressure switches activate the pump when pressure drops and
shut it off at set pressure.


11. Which safety equipment is REQUIRED when working on electrical
pump components?

, A. Rubber boots
B. Safety glasses only
C. Lockout/tagout
D. Hearing protection
✅ ANSWER : C
Explanation: Lockout/tagout prevents accidental energizing of electrical
equipment.


12. A 1 HP pump draws excessive amps. What is the MOST likely cause?
A. High voltage
B. Incorrect pipe size
C. Low voltage
D. New pressure tank
✅ ANSWER : C
Explanation: Low voltage increases current draw and motor heating.


13. What does “drawdown” refer to in a pressure tank?
A. Total tank size
B. Amount of usable water between cycles
C. Pump horsepower
D. Well depth
✅ ANSWER : B
Explanation: Drawdown is the usable volume before the pump restarts.


14. Which component controls pressure range in a pump system?
A. Pressure tank
B. Check valve
C. Pressure switch
D. Foot valve
✅ ANSWER : C
Explanation: The pressure switch sets cut-in and cut-out pressures.
