Abstract
A hydrant comprising a housing forming a reservoir; and a piston configured to force residual fluid out of the reservoir to an outlet and to allow supply fluid to flow from an inlet through the piston to the outlet when the piston is actuated in the housing to a first position, and when the piston is actuated in the housing to a second position, to restrict flow of the supply fluid to the outlet and to allow at least a portion of the supply fluid that has flowed from the inlet to flow into the reservoir thereby becoming new residual fluid.
