The minimum space above the test ports of a backflow assembly is _________________.

• A. 6 inches
• B. 12 inches
• C. 30 inches

Answer: (B)

The minimum space above the test ports of a backflow assembly is specified as 12 inches to ensure proper access and functionality of the assembly. This clearance allows for the necessary room to perform testing and maintenance procedures without obstruction. It is essential for personnel to be able to easily read gauges, access the ports for testing equipment, and perform any adjustments or repairs if needed safely. Adequate space helps mitigate risks associated with working on plumbing systems, ensuring that there are no unforeseen hazards that could arise if the assembly were installed too closely to ceilings, walls, or other structures. This regulation reinforces the importance of safety and efficiency in plumbing practices, aligning with code requirements for backflow prevention devices.
