Toilet Parts: Names & Functions

Modern toilets typically comprise two primary components: the toilet tank and the bowl. The following section will explore these parts in detail, highlighting their functions.

Toilet Tank Parts

Flush Valve

A flush valve is a self-closing valve that lets out a bunch of water when you flush a toilet or urinal. It is found inside the tank of a toilet or the body of a urinal. You usually activate it with a lever or a button.

If the flush valve gets old or corroded, it can leak water into your toilet, causing noise and wastage. Over time, corrosion can wear it down, creating a gap between the tank and bowl, making water escape continuously.

Fill Valve

The fill valve is a vital part of your toilet that regulates the entry of fresh water into the tank. Typically located on the left side, it connects to a supply tube and a fixture shutoff valve. Sometimes called a ballcock, it got its name from an older design.

As your toilet flushes, the fill valve opens and closes. With time, it can wear out and require replacement. If your current valve has a float ball, consider upgrading to a more reliable modern version with its integrated float cup.
