UPDATE THIS YEAR
Texas Water Well Pump Installer License Exam
SUMMARIZED EXAM TOPICS (Point Form – Accurate for Texas License Coverage Areas)
• Licensing and Regulation (TDLR oversight, Occupations Code Chapter 1902, license validity 1-2
years, renewal requirements, continuing education, examination passing score 70%)
• Pump Types and Applications (submersible pumps for deep wells, jet pumps for shallow wells
≤25 ft, centrifugal pumps, vertical turbine pumps, positive displacement pumps)
• Installation Practices (pitless adapters, sanitary well caps, torque arrestors, drop pipe materials
(PVC, steel), waterproof splice kits, pump setting depth minimum 25 ft above bottom)
• Well Protection and Sanitation (well seals, surface grading, separation distances: septic tank 50
ft, drainfield 100 ft, shock chlorination, bacteria elimination)
• System Components (pressure tanks, pressure switches, check valves, foot valves, pressure
relief valves, flow meters, motor starters, overload protection)
• Hydraulics and Sizing (total dynamic head TDH, static head, friction losses, pump curves, flow
rate vs head, specific capacity, drawdown, NPSH)
• Electrical Requirements (NEC compliance, single-phase motors for residential, voltage matching,
grounding, surge protection, VFD operation, overload protection)
• Well Testing and Troubleshooting (pump tests, drawdown tests, static water level
measurement, short cycling causes, cavitation diagnosis, low pressure causes)
• Water Quality Considerations (corrosive water requiring stainless steel, iron bacteria treatment,
sand control, well development, regular water testing)
• Safety and Documentation (lockout/tagout, lifting equipment, completion reports, invoices,
chain of custody, contaminated well reporting)
1. What is the primary purpose of a water well pump installer license in Texas?
A) To generate revenue for the Texas Department of Licensing and Regulation
B) To ensure pumps are installed safely and meet state standards
C) To restrict competition among pump installers
D) To register all water wells in the state
Answer: B
, Page 2 of 114
Rationale: The license verifies competency in proper installation practices to protect public health and
groundwater resources .
2. Who regulates water well pump installers in Texas?
A) Texas Commission on Environmental Quality (TCEQ)
B) Texas Water Development Board (TWDB)
C) Texas Department of Licensing and Regulation (TDLR)
D) Texas Ground Water Association (TGWA)
Answer: C
Rationale: TDLR oversees licensing, rules, and enforcement for water well pump installers under
Occupations Code Chapter 1902 .
3. A pump installer is preparing to install a submersible pump in a residential well. At what minimum
depth above the well bottom should the pump typically be set?
A) 10 feet above the bottom
B) 15 feet above the bottom
C) 25 feet above the bottom
D) 50 feet above the bottom
, Page 3 of 114
Answer: C
Rationale: Setting the pump above the well bottom prevents sediment from being drawn into the pump,
extending pump life and efficiency .
4. What is the primary function of a pitless adapter in a water well system?
A) To increase water flow rate from the well
B) To provide a sanitary, frost-free connection between the well casing and the water line
C) To filter sediment before water enters the distribution system
D) To regulate pump cycling frequency
Answer: B
Rationale: Pitless adapters allow water to flow from the well below the frost line to the distribution
system while preventing contamination and freezing .
5. According to Texas regulations, what is the passing grade for the water well pump installer
examination?
A) 65%
B) 70%
C) 75%
, Page 4 of 114
D) 80%
Answer: B
Rationale: Texas Administrative Code Section 76.23 specifies that a passing grade for the examination is
70% .
6. How often should a water well be inspected for mechanical integrity?
A) Every 6 months
B) At least once a year
C) Every 2 years
D) Only when problems occur
Answer: B
Rationale: Annual inspections help ensure that the well and pump system operate efficiently and that
potential issues are identified early .
7. What is the primary cause of pump cavitation in a water well system?
A) Excessive pump speed
B) Low water level or poor suction conditions
C) High water temperature
