Flush Valve
Definition and meaning of Flush Valve in real estate.
A flush valve is the mechanical assembly located at the bottom of a toilet tank that opens to release water into the toilet bowl when the flush lever is pulled.
In more detail
This valve controls the flow of water needed to empty the bowl and flush waste into the sewer system. It consists of an overflow tube, a valve seat, and a sealing mechanism such as a rubber flapper or stopper. When a homeowner pushes the toilet handle, a chain lifts the flapper off the valve seat, allowing tank water to rush down.
A malfunctioning flush valve can lead to water constantly leaking from the tank into the bowl, resulting in wasted water and high utility bills.

Frequently asked questions
How do you know if a toilet flush valve needs to be replaced?
If you hear water running constantly, or if a simple test of putting food coloring in the tank shows color leaking into the bowl without flushing, the valve or its seal is likely damaged.
Are flush valves a standard size?
Most residential toilets use a two-inch or three-inch flush valve, so homeowners should measure their current valve before purchasing a replacement part.
