You probably don’t think of a toilet as a machine. But that’s what it is. You press down the flush lever, and the toilet does the work.
Most toilets have two main parts-a tank and a bowl. The tank sits on the back of the toilet bowl. Both contain water. The bottom of the tank has an opening with a plug. The plug keeps the water in the tank from flowing into the bowl. Pushing down the lever to flush the toilet lifts up the plug.
Water then rushes out of the tank. It flows into the toilet bowl through small holes all around the rim of the bowl.
The fresh water pushes the dirty water into the drainpipe. The plug closes when the tank is empty. Fresh water then flows through an inlet tube into the tank. And the tank is ready for the next flush.
