Why does my backflow preventer have to be tested every year?

Mechanical backflow preventers have internal seals, springs, and moving parts that are subject to fouling, wear, and fatigue, which can lead to failure. Therefore, all backflow preventers must be tested with properly calibrated gauges and equipment at least once annually to ensure that they are functioning properly.
