Backflow Prevention Practice Exam

Before the physical test of a backflow preventer may begin, what is the first step the tester must take?

1. Begin completing the test report form

2. Conduct a downstream plumbing hazard inspection

3. Obtain a repair kit

4. Obtain permission to shut-down the water service

The correct answer is: Obtain permission to shut-down the water service

The first step a tester must take before performing a physical test of a backflow preventer is to obtain permission to shut down the water service. This procedure is essential to ensure safety and compliance with local regulations or service agreements. By securing permission, the tester ensures that they are authorized to perform the test, which may temporarily disrupt water service to customers or properties relying on that system. Obtaining permission also allows the tester to inform affected users of the upcoming interruption, helping to mitigate any potential issues, such as inconvenience to residents or businesses. This step is critical to uphold the responsibility of managing the water supply and protecting public health, as any unauthorized action could lead to liability concerns or disputes with consumers or regulatory bodies.
