A. During air pressure testing of a new valve in the closed position, leakage past the seats is collected and bubbled through water. To qualify as bubble-tight, no bubble should be observed in a prescribed period.
A. When high-speed water is forced to change direction or stopped abruptly, it causes a sudden bounce-back known as water hammering. The check valve acts as a cushion for shockwaves and avoids damage.
