What should be done annually to ensure the functionality of a dry pipe valve?

• A. Test main pipe pressures
• B. Open and close it periodically
• C. Inspect surrounding areas
• D. Calibrate the alarm system

Answer: (B)

To ensure the functionality of a dry pipe valve, it is essential to open and close it periodically. This practice is crucial because the dry pipe valve is designed to control water flow from a supply pipe into the sprinkler system, and if not exercised, its mechanical parts can seize or become sluggish due to inactivity. By periodically opening and closing the valve, potential issues such as sediment buildup or corrosion can be identified and addressed, ensuring that the valve will operate effectively when needed. Regular operation also helps to verify that the valve seals properly and that any pneumatic control systems associated with the valve are functioning as intended. This maintenance step is integral to maintaining the reliability of the fire protection system since a malfunctioning valve can lead to ineffective fire suppression during an emergency situation. Maintaining the valve in this way ensures readiness and compliance with inspection protocols that demand operational checks for components of fire safety systems.
