How should the temporary bypass hose be connected if shut-off valve #2 is leaking during a differential pressure relief valve test?

• A. Test cock #1 to test cock #2
• B. Test cock #1 to test cock #3
• C. Test cock #1 to test cock #4
• D. Test cock #2 to test cock #4

Answer: (C)

During a differential pressure relief valve test, if shut-off valve #2 is leaking, it's essential to configure the connections properly to ensure accurate results and prevent backflow issues. Connecting test cock #1 to test cock #4 allows for a bypass that reroutes water through the system without compromising pressure readings. This connection keeps the test environment stable while isolating the leak caused by shut-off valve #2. Each test cock has a specific function in the system, and using the correct combination helps maintain the integrity of the testing process. By utilizing test cock #4, which is intended for this situation, any influence from the leaking shut-off valve can be effectively mitigated. This ensures that the pressure relief valve test yields valid data and the system operates safely.
