Abstract
A self-draining hydrant comprising a supply line coupled to an outlet and a housing adapted for placement in the ground and for coupling to a water supply. The housing can selectively provide water from the water supply to the supply line and has a reservoir for receiving drained water from the supply line. A piston is movable in a direction of travel from a first position to a second position within the housing for engaging the drained water and expelling it from the reservoir. The piston has a seal for engaging the housing to provide a seal with respect to the drained water. The housing has at least one slot extending in the direction of travel and engageable by the seal for permitting drained water to pass the seal.
