What is the height requirement for gravity tanks above the highest sprinkler head?

• A. 15 feet
• B. 20 feet
• C. 25 feet
• D. 30 feet

Answer: (C)

The height requirement for gravity tanks above the highest sprinkler head is 25 feet. This height ensures that there is adequate water pressure for effective operation of the sprinkler system. The 25-foot elevation allows the system to maintain the necessary hydraulic pressure to properly distribute water when the system is activated. Considerations for this requirement include the need for sufficient pressure to overcome friction loss in the piping system and ensure that the water can reach all the designated areas of coverage. Gravity tanks, which rely on gravitational force to provide water to fire suppression systems, must be positioned at this specific height to maintain the functionality and reliability of the sprinkler system.
