1. Which of the following is the primary purpose of a submersible
well pump?
a) To remove sediment from water
b) To increase water temperature
c) To lift water from a well to the surface
d) To filter water
Rationale: Submersible pumps are installed inside the well and are
designed to push water to the surface efficiently, not to heat or filter it.
2. What is the recommended minimum distance between a well and
a septic tank in Michigan?
a) 25 feet
b) 50 feet
c) 100 feet
d) 200 feet
Rationale: State regulations require a minimum separation of 100 feet
to prevent contamination of well water.
3. Which type of well casing is most resistant to corrosion and
chemical damage?
, a) Wood
b) Concrete
c) PVC (polyvinyl chloride)
d) Steel
Rationale: PVC is chemically resistant, non-corrosive, and commonly
used in modern well construction.
4. What is the purpose of a check valve in a well pump system?
a) To regulate water pressure
b) To filter debris
c) To prevent backflow of water into the well
d) To increase water flow
Rationale: Check valves prevent water from flowing back into the well,
maintaining system pressure and preventing pump damage.
5. What is the primary function of a pressure tank in a well system?
a) To store drinking water
b) To maintain system pressure and reduce pump cycling
c) To filter impurities
d) To heat water
Rationale: The pressure tank allows the pump to turn on and off less
frequently, extending its lifespan and maintaining consistent pressure.
6. Which type of pump is generally used for wells deeper than 25
feet?
a) Jet pump
b) Submersible pump
c) Hand pump
d) Gravity pump
Rationale: Jet pumps are suitable for shallow wells, while submersible
pumps are designed for deeper installations.
, 7. What is the most common cause of well pump failure?
a) Overheating due to continuous operation
b) Corrosion of pump casing
c) Electrical issues or dry running
d) Sediment in water
Rationale: Electrical failures and dry running (pumping without water)
are leading causes of well pump failure.
8. Which component protects a pump motor from overheating?
a) Flow switch
b) Pressure switch
c) Thermal overload protector
d) Check valve
Rationale: Thermal overload protectors detect excessive heat and shut
off the motor to prevent damage.
9. Which well construction type typically produces the cleanest
water?
a) Dug well
b) Driven well
c) Drilled well
d) Spring-fed well
Rationale: Drilled wells extend deep into aquifers and are less
susceptible to surface contamination.
10. How is well yield typically measured?
a) Gallons per minute (GPM)
b) Liters per second
c) Both A and B
d) Cubic feet per hour
