All About Fill Valves

You'll find the fill valve inside your toilet tank. It's the tall plastic mechanism that usually sits on the left side of the tank. When you flush the toilet, this valve opens up to let fresh water refill both the tank and the toilet bowl. Once the water gets to the exact right height a float attached to the valve automatically shuts the water off.

The word valve comes from the latin word valva, which means a folding door. The modern floating fill valve was invented in the early 1900s to automate the toilet refilling process. Before that, toilets were much harder to operate. Today, every standard gravity toilet uses some version of this clever device.
