  2. Air lock - Wikipedia

    en.wikipedia.org/wiki/Air_lock

    As more water flows down, the upward leg after the second low point fills up. This exerts a pressure on the trapped air from the water on either side. If there is more water pressure from the section after the trapped air, then a full air lock is formed, and the water level stops at the first high point and no further water can flow.
