Rhode Island Journeyman Plumber Practice Exam

How often should backflows be inspected?

1. Monthly

2. Yearly

3. Only during install and repairs

4. Once every two years

The correct answer is: Yearly

The correct choice is yearly for backflow inspections, which aligns with industry standards and regulatory requirements. Annual inspections are crucial because they ensure the proper functioning of backflow prevention devices, which protect potable water supplies from contamination. These devices can face wear and tear over time, and regular inspections help identify any issues before they pose a risk to health and safety. In many jurisdictions, including Rhode Island, this annual requirement is mandated by plumbing codes and public health regulations. By adhering to this timeline, plumbers can ensure compliance and uphold the integrity of the water supply systems. Such inspections involve checking the device for leaks, verifying the proper positioning and operation, and testing its effectiveness in preventing backflow. Other frequencies, such as monthly or only during installation and repairs, may not adequately address the ongoing risk that could arise between inspections. While biennial inspections can provide some level of oversight, they might not be frequent enough to catch problems that could potentially develop in a shorter timeframe. Regular yearly checks strike a balance between thorough oversight and practical scheduling for plumbing professionals.
