Which condition indicates a problem with sprinkler heads?

• A. New paint on heads
• B. Leaking
• C. Properly aligned caps
• D. Clean corrosion-free surfaces

Answer: (B)

Leaking is the telltale sign of a problem. Sprinkler heads are supposed to remain sealed and dry until heat from a fire activates them. If water is visible around a head or dripping from it, the seal or gasket is compromised, or the head is damaged or improperly installed, so it cannot reliably control water release when needed. This not only wastes water and risks water damage but also means the system could fail to operate correctly in a fire. Other conditions listed—paint on the heads, properly aligned caps, or clean, corrosion-free surfaces—don’t indicate a leakage issue; they suggest the head is intact and not currently failing.
