How far apart should hangers be placed for a 1¼" diameter pipe?

• A. 2' - 3'
• B. 3' - 4'
• C. 4' - 5'
• D. 1½' - 5'

Answer: (B)

For a 1¼" diameter pipe, the standard practice is to space hangers between 3 to 4 feet apart. This spacing ensures adequate support while allowing for expansion and movement of the piping system during operation. Proper spacing helps prevent sagging and reduces stress on the joints and connections, which can lead to leaks or failures over time. The hanger spacing is also influenced by the material of the pipe and the type of application, but for standard steel or PVC pipes, the spacing guideline falls within this range. Adhering to these recommendations helps ensure the durability and safety of the sprinkler system. The other options suggest either too short or too long spacing that could fail to provide the necessary support and stability for the pipe.
