A toilet consists of several key components that work together to facilitate its function. The main parts include the toilet bowl, which holds water and waste, and the tank, which stores water for flushing. Inside the tank, you'll find the flapper, a rubber valve that opens to release water into the bowl when the toilet is flushed. Another important component is the fill valve, which refills the tank after a flush. The flush handle is used to activate the flushing mechanism, while the trapway is the curved pipe that connects the bowl to the drainage system, ensuring waste is removed efficiently.
