What is a common indication that a sprinkler system may need maintenance?

• A. Presence of water in the vicinity of the system
• B. Visual inspection showing no signs of wear
• C. Uninterrupted water flow during testing
• D. Visible signs of rust or corrosion on any components

Answer: (D)

Visible signs of rust or corrosion on any components of a sprinkler system are a strong indication that maintenance is needed. These signs suggest that metal components are potentially deteriorating, which can compromise the integrity and functionality of the system. Rust and corrosion can lead to leaks, reduced water flow, and complete failures of the system during operation. Regular maintenance is essential to ensure that all components remain in good condition and effectively protect against fire hazards. The presence of water in the vicinity of the system might raise concerns but does not directly indicate that maintenance is required without further investigation. A visual inspection showing no signs of wear would typically suggest that the system is in good condition rather than needing attention. Uninterrupted water flow during testing is a positive indicator of system operation and reliability, further indicating that no issues exist that would require maintenance.
