Giải thích
An island or loop vent rises as high as possible under the counter, returns downward, and then connects to a vent line, which is the method developed for fixtures with no adjacent wall. A circuit vent serves a battery of floor-set fixtures, a yoke vent relieves pressure between a drainage stack and its vent stack, and a vent stack is the vertical vent serving a whole drainage stack rather than a single island fixture.
