Gauges on a wet-pipe sprinkler system shall be inspected?

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

Answer: (B)

Gauges on a wet-pipe sprinkler system show the water pressure and residual pressure, which must stay within the designed range so sprinklers will operate properly when needed. Because these systems are always filled with water and under pressure, even small leaks or partially closed valves can cause a noticeable pressure drop. Regular visual checks of the gauges help catch these issues before an incident occurs, ensuring the system remains ready to deliver water. Monthly inspection is the standard practice because it provides timely monitoring without being overly burdensome. Checking more often would be unnecessary for most gauge readings, while checking less often could allow a developing problem to go unnoticed for an extended period. Annual checks are not frequent enough to ensure ongoing readiness.
