fill valve

A **fill valve** is an essential component of a toilet’s tank that controls the flow of water into the tank after each flush. It refills the tank to the correct water level, ensuring the toilet is ready for the next use. Fill valves come in various designs, including traditional ballcock valves and modern float-cup models, and they can be adjusted to regulate water flow and conserve water. Proper maintenance or replacement of a faulty fill valve helps prevent running toilets, leaks, and water wastage.
