A flushing hydrant is a hydrant that is used for flushing a water line of silt, rust, debris, or stagnant water.
Many water utilities use standard fire hydrants for flushing their lines.
Specialized flushing hydrants are often smaller and less expensive than a fire hydrant to reduce cost where fire fighting use is not needed or practical.
Flushing hydrants are commonly installed at the end of dead-end water lines.
