1. What is the primary purpose of a backflow prevention device?
A. To increase water pressure
B. To prevent contamination of the potable water supply
C. To filter sediments
D. To regulate water temperature
Prevents reverse flow of potentially contaminated water into the
public water system.
2. Which of the following is a common type of backflow prevention
assembly?
A. Butterfly valve
B. Reduced Pressure Principle Assembly (RP)
C. Gate valve
D. Pressure relief valve
RP assemblies are widely used to protect against high- and low-
hazard contamination.
,3. Cross-connections in plumbing systems can lead to:
A. Increased water flow
B. Reduced water pressure
C. Backflow contamination
D. Water hammer
Cross-connections create potential paths for contaminants to enter
the potable water supply.
4. A double check valve assembly is suitable for which type of
hazard?
A. High hazard
B. Low to moderate hazard
C. Extreme hazard
D. Fire suppression systems
Double check valves are designed for low- to moderate-hazard
applications.
5. The relief valve on a reduced pressure backflow assembly opens
when:
A. Pressure is normal
B. Differential pressure drops below set point
C. Water flow stops
D. The check valves are closed
The relief valve activates to discharge water when backflow
creates unsafe pressure conditions.
6. What is the first step in repairing a backflow assembly?
A. Reinstall the device
B. Shut off the water supply
C. Remove all valves
, D. Flush the system
Shutting off water ensures safety and prevents contamination
during repair.
7. Backflow can occur due to:
A. Gravity only
B. High water pressure only
C. Backsiphonage and backpressure
D. Water filtration
Backflow mechanisms include both backsiphonage (suction) and
backpressure (pressure-driven).
8. When testing a backflow assembly, what is crucial to ensure
accurate results?
A. Cleaning the outside
B. Using a properly calibrated test kit
C. Shutting off the entire building water
D. Only checking visually
Accurate readings require calibrated testing equipment.
9. How often are most backflow prevention assemblies required to
be tested in Georgia?
A. Every month
B. Annually
C. Every five years
D. Every two years
Annual testing ensures continued compliance and functionality.
10. What is the purpose of the test cocks on a backflow
assembly?
A. Drain water
