Which item must be inspected on a monthly basis according to the listed maintenance guidelines?

• A. Air pressure gauges
• B. Hose houses
• C. Wet barrel hydrants
• D. Monitor nozzles

Answer: (A)

Regularly verifying the indicators that show system readiness is essential, and the air pressure gauge is the direct readout of the charged air in the system. Inspecting this gauge monthly ensures the air charge is within the required range and can reveal leaks, loss of charge, or a stuck valve before an actual discharge occurs. If the gauge drops or reads inaccurately, the dry pipe or related system may not fill promptly when needed, compromising response time. The other items—hose houses, wet barrel hydrants, and monitor nozzles—have maintenance frequencies that are not typically monthly and do not provide a direct, reliable daily readiness indication in most guidelines. Therefore, the item that must be inspected monthly is the air pressure gauge.
