Answer: (C)

The interval for conducting a main drain test when the sole water source is through a backflow preventer is set at quarterly. This frequency is crucial because the backflow preventer is a critical component that helps protect the potable water supply from contamination. Regular testing ensures that the system is functioning properly and that any potential issues can be identified and addressed in a timely manner. Conducting the main drain test quarterly allows for an effective monitoring schedule that is in line with recommended practices for systems that utilize backflow protection. By adhering to this interval, facility managers and fire protection professionals can maintain compliance with relevant standards and ensure the reliability of the water-based fire suppression system. This proactive approach helps to ensure that the system remains operational and that the safety features are effective in the event of a fire emergency.
