Cross Connection Practice Exam

Which of the following is a component of a Cross Connection Control program?

1. Installation of new pipelines

2. Annual testing of backflow assemblies

3. Removing old fixtures

4. Daily monitoring of water usage

The correct answer is: Annual testing of backflow assemblies

The annual testing of backflow assemblies is a vital component of a Cross Connection Control program because it ensures that backflow preventers are functioning correctly to protect the potable water supply. Backflow assemblies are designed to prevent contaminated water from flowing back into the clean water supply due to pressure changes or back siphonage. Regular testing confirms that these devices are sealed properly and operate as intended, helping to maintain the safety and quality of drinking water. The other components listed do not directly relate to the specific goals of a Cross Connection Control program. For instance, while the installation of new pipelines can be a part of broader water system management, it does not specifically address cross-connections or their control. Removing old fixtures might relate to plumbing updates or maintenance but does not encompass the necessary preventative measures required by cross connection control protocols. Daily monitoring of water usage, although important for overall water management, is not specific to the control of cross connections and preventing backflow events. Therefore, annual testing stands out as a critical practice aimed explicitly at safeguarding public health regarding water quality.
