The monthly external inspection of a dry valve intermediate chamber should indicate which condition?

• A. Not Leaking
• B. Leaking
• C. Blocked
• D. Overheating

Answer: (A)

In this monthly external check, you’re looking for the integrity of the dry valve’s intermediate chamber. The chamber must stay dry on the outside because it holds air under pressure to help keep the valve closed until sprinkler activity requires it to release. If there’s any external moisture or dampness, that indicates a leak in the packing or seals, which can cause loss of air pressure and unreliable operation when the system is activated. So the best condition to observe is that the chamber is not leaking. A leaking sign would show up as moisture, dampness, or water around the chamber, signaling a service issue. The other conditions (blocked or overheating) aren’t the expected exterior condition for this inspection and aren’t what this monthly check is meant to document.
