A. Siphoning flush uses a mechanism to produce a vacuum-like effect to dispel waste. Upon flushing, a high volume of water enters the bowl and gets pulled down through a standard 2-inch trapway, filling a siphon tube. When that tube is full, the vacuum-like effect is created and waste is dispersed. Siphoning stops once air hits the tube. This system works well, but requires a lot of water and is problematic when 1.6 gallons of water or less is used. The small trapway, which is needed to get that vacuum effect, clogs more frequently, requiring a second flush that wastes more water. Gravity flush opens a flush valve and releases between 1.28 and 1.6 gallons of water from the tank behind the toilet seat. As the water flows into the toilet bowl, gravity pulls the waste material down through the opening at the bottom of the bowl into the drain. A curved pipe called a trap at the base of the bowl near the floor slopes down and then upward to transport waste from the drain into the sewage system. When the bowl fills with water at the end of the cycle, it prevents noxious sewer gases from contaminating the air.
