A ventilation cap includes a tube portion, a vent portion, and an upper portion. The tube portion is configured to releasably engage with a vent pipe. The vent portion extends from the tube portion to define a common pathway formed therein. The vent portion has at least three interconnected adjacent sides. Each of the sides includes one or more upright ribs, and multiple contiguous ribs laterally extending from the upright ribs to define openings in fluid communication with the common pathway. The contiguous ribs at one or more sides have an intermediate segment with an increased cross-sectional area. The contiguous ribs taper laterally from the intermediate segment to ends. The upper portion is disposed above the vent portion and connected to an upper end of the upright ribs.
