Gauges on dry, preaction, and deluge sprinkler systems are inspected how often?

• A. Weekly.
• B. Quarterly.
• C. Biannually.
• D. Monthly.

Answer: (D)

Gauges on these systems are checked monthly to ensure the charged pressure in the piping is correct and that the gauge is functioning and not leaking or stuck. In dry, preaction, and deluge systems, the piping is kept at a standby pressure (air or inert gas in dry and preaction, system pressure in deluge) and water release depends on accurate pressure readings. Regular monthly inspection catches drops in pressure, gauge misreads, or leaks before a fire event, ensuring the system will respond promptly when needed. Weekly checks would be excessive for most systems, while quarterly or biannual checks could miss gradual pressure loss or gauge failure. Monthly is the appropriate balance to maintain readiness.
