When should testable backflow prevention devices be tested?

• A. Every six months
• B. Annually
• C. Every two years
• D. Whenever repairs are made

Answer: (B)

Testable backflow prevention devices should be tested annually to ensure their proper function and to prevent contamination of the potable water supply. Annual testing is recommended as it allows for regular inspection and maintenance of these devices, which can be susceptible to wear, damage, or malfunction over time. This timeframe ensures that any issues are identified and addressed promptly, safeguarding public health. While other options suggest testing at different intervals, the annual requirement aligns with best practices and regulations set forth by plumbing codes and health authorities, which emphasize the importance of routine checks for backflow devices to maintain the integrity of drinking water systems.
