1. A jumper drain for a refrigerator appliance that provides fluid communication between a storage compartment and a machine compartment via a drain that collects and transfers liquid condensate from an evaporator, the jumper drain comprising:
a housing extending longitudinally between opposite first and second ends and defining a cavity therein, the cavity being in fluid communication with the storage compartment;
an inlet adjacent the first end and extending from the housing and in fluid communication with the cavity;
an outlet adjacent the second end and extending from the housing and in fluid communication with the cavity, the outlet being disposed at a location that is offset from the inlet; and
a pressure equalizer opening formed in a planar face of the housing provided at the second end thereof, wherein the pressure equalizer opening is configured to provide fluid communication between the cavity and an ambient environment external to the refrigerator appliance in order to equalize a pressure differential within the refrigerator appliance,
wherein a wall projects outwards from an external surface of the planar face in a direction away from the housing, and wherein the wall peripherally surrounds the pressure equalizer opening.
