Which item is used to test a wet pipe system to prevent unseating and the alarm?

• A. Wooden wedges or metal hooks
• B. Copper wires
• C. Glass beads
• D. Plastic ties

Answer: (A)

When checking a wet-pipe system, you want to verify piping integrity without triggering waterflow alarms or dislodging sprinkler heads. Wooden wedges or metal hooks serve as temporary restraints that hold components (such as the valve or clapper area) in a safe position during the test. This prevents unintended movement, keeps the system from releasing water or triggering the alarm prematurely, and allows you to accurately assess for leaks or faults. They’re easy to remove once testing is complete, restoring normal operation. The other options don’t provide the practical, temporary restraint needed for this specific testing step.
