An impulse-sinking hydrant having an upright cylindrical housing with a movable piston disposed therein and formed with a radial passageway and an upright stem having a first passageway communicating with the radial passageway, the upright stem extending above the housing in an upper position of the piston. The upper end of the housing communicates with a pressure-accumulative reservoir through a second passageway which lies in registration with the radial passageway when the piston is in the upper position. A supply conduit carrying water under pressure communicates with the reservoir through a third passageway and with the interior of the housing through a fourth passageway feeding into the lower end thereof for displacing the piston upwardly. A valve member vertically disposed in the third passageway is displaceable by the water from the supply conduit into a radial passageway blocking position for allowing the water to feed into the reservoir and, upon equalization of the water pressure in the reservoir with the water pressure in the supply conduit, the valve being displaceable by gravity into a supply conduit blocking position for allowing the water from the reservoir to feed into the radial passageway.
