Are coach screw rods permitted for the support of sprinkler system pipes larger than 4 inches?

Coach screw rods are not permitted for the support of sprinkler system pipes larger than 4 inches due to safety and code compliance reasons. Larger pipes typically carry more water and can exert significant weight and stress on the support system. Proper support methods are crucial to ensure the integrity and reliability of the sprinkler system. Using inadequate support such as coach screw rods can lead to failures in the system, potentially resulting in leaks or system collapses during operation.

In fire protection systems, adherence to established standards and building codes is vital for maintaining operational safety and effectiveness. Larger sprinkler pipes require specific types of bracing and support that can adequately handle their weight and the dynamic forces that may occur during operation.

Thus, the prohibition against using coach screw rods for larger pipes is in place to ensure the safety and functionality of fire protection systems, emphasizing the need for appropriate materials and methods in compliance with relevant codes and regulations.
