What is DA FORM 3943?

DA FORM 3943, officially titled “Annual Dry Pipe Valve Inspection and Tripping Test”, is a standardized form used by the USACE to document the inspection and testing of dry pipe valves. These valves are an integral part of fire suppression systems, particularly in areas where the pipes cannot be filled with water due to freezing temperatures.

Importance of Dry Pipe Valve Inspection and Testing

Dry pipe valves are used in sprinkler systems that are installed in environments where water in the pipes can freeze. These systems are filled with air or nitrogen under pressure, and the dry pipe valve prevents water from entering the pipe until a fire triggers the system.

Why Regular Inspection and Testing Are Necessary

  1. Prevent Malfunction: Regular inspections help identify any potential issues that can cause the valve to malfunction, leading to system failure during a fire.
  2. Ensure Fast Response: The tripping test ensures that the valve will open promptly when needed, allowing water to flow into the system and extinguish the fire effectively.
  3. Compliance with Safety Standards: Regular testing and inspection are often required by safety regulations to maintain the operational readiness of fire suppression systems.

How to Conduct an Annual Inspection and Tripping Test

Conducting the annual inspection and tripping test involves several critical steps, each of which must be documented on DA FORM 3943.

Pre-Inspection Steps

  1. Review Previous Reports: Check past inspection reports for any issues or repairs that have been noted.
  2. Prepare the System: Ensure that the system is set up and ready for testing, including notifying any affected parties that the system will be temporarily offline.

Inspection and Testing Process

  1. Visual Inspection: Examine the dry pipe valve and its components for signs of physical damage, corrosion, or leakage.
  2. Operational Test: This involves triggering the valve to ensure it trips (opens) correctly and at the right pressure.
  3. Resetting the System: After the test, the system must be reset to its normal operational state.

Documenting on DA FORM 3943

  • Record the Findings: All observations, test results, and any anomalies found during the inspection should be recorded.
  • Action Taken: Note any repairs or adjustments made to the system.
  • Certification: A qualified inspector must sign and date the form, certifying that the inspection and test have been conducted according to the required standards.


The Annual Dry Pipe Valve Inspection and Tripping Test, as documented on DA FORM 3943, is a critical process that ensures the safety and functionality of fire suppression systems in cold environments. By regularly conducting these inspections and tests, facilities can maintain high safety standards and be prepared for emergencies. This form, along with its detailed record-keeping, helps the USACE and other organizations keep track of the health of their dry pipe systems, ensuring that they function optimally when needed the most.

Remember, the safety of your facility and the effectiveness of your fire suppression system depend significantly on these annual inspections and tests. Always ensure that they are conducted by qualified personnel and documented thoroughly on DA FORM 3943.
