The Handle Moves the Flush Valve

A chain runs from the inside of the flushing handle, down the side of the toilet tank to the flush valve. Pushing on the handle will pull that chain up and also pull up the flush valve. Under the flush valve is a drain hole usually two to three inches wide.

Water Enters the Drain Hole

Once the drain hole is uncovered, the sitting water in the tank enters the toilet bowl through this hole. Toilets are shaped so that the water enters the rim and swirls around, then flows down to the larger hole at the bottom of the toilet.

Waste is Swept Away

The hole at the bottom of the toilet actually has a name! It is called the siphon jet. When the water from the tank enters the toilet bowl, it does so in less than three seconds. This large amount of water entering so quickly creates what is called a siphon effect. The effect happens when the water and waste rushes into the siphon hole and is jetted into the siphon tube. Waste and water is sucked right out of the toilet bowl.
