What should you do if the time delay fails to discharge?

• A. Reset timer
• B. Open time delay bypass valve
• C. Close main valve
• D. Bypass entire system

Answer: (B)

When a time delay element in a discharge line isn’t releasing water, the flow path through that delay is effectively blocked. Opening the time delay bypass valve creates a direct path around the delay, restoring immediate discharge to the intended area. This lets the system function as designed without waiting for the delay that isn’t working. Resetting the timer might help if the issue is electrical, but it doesn’t fix the blocked hydraulic path, and closing the main valve or bypassing the entire system would stop or bypass essential control features, which isn’t appropriate for normal operation.
