Why is it important to flush test cocks in the correct sequence?

• A. To prevent air from entering the system
• B. To avoid damage to the device
• C. To ensure accurate measurement
• D. To speed up the testing process

Answer: (C)

Flushing test cocks in the correct sequence is essential to ensure accurate measurement. During the testing of backflow prevention devices, the sequence in which the test cocks are flushed affects the pressure readings that are taken. If the test cocks are not flushed in the proper order, it can lead to inaccurate pressure measurements and faulty test results. This is because improper flushing could allow for the presence of trapped debris or air pockets, which can skew the data collected during the testing process. Therefore, following the correct flushing sequence helps maintain the integrity of the testing procedure and ensures that the results reflect the true performance of the device being tested. Accurate measurements are vital for determining whether the backflow prevention mechanism is functioning properly and providing the necessary protection against contamination in the water supply.
