Even at that, water hammer may occur at valves with air chambers installed.
Why does my water hammer when I Turn Off the tap?
Ordinarily, plumbing pipes are designed to pressurise the water passing through them. Hence, they rush through the tap when you open it. Turning the tap off suddenly makes the water collide with the closed valve, hence producing a hydraulic shock.
