The volume of water in the tank, its height above the bowl, restrictions or blockages between the tank and the bowl, or within the bowl all limit the speed and amount of work the tank water can perform. If your toilet is less than ten years old, you may have a first generation 1.6 gallon low flush toilet. These toilets were mandated by the 1992 Energy Policy Act in an effort to save water. Traditional toilets used 3.5 gallons of water per flush.
At the top of the toilet bowl is a rim with many angled drain holes that are fed from the tank, which fill, rinse, and induce swirling in the bowl when it is flushed. Mounted above the toilet is a large holding tank with approximately 1.2 to 1.6 U.S. gallons (4.5 to 6.1 L) of water in modern designs. This tank is built with a large drain 2.0 to 3.0 inches (5.08 to 7.62 cm) diameter hole at its bottom covered by a flapper valve that allows the water to rapidly leave the holding tank.
