A vent valve includes a vent body including an outlet and at least one inlet, a main chamber, a main closable device movable from an open position to allow fluidic communication between the main chamber and the outlet, to a closed position to block fluidic communication between the main chamber and the outlet, and a first tubing having a first end and a second end, the first end connected to a first inlet, the second end spaced from the vent body, the first tubing further including a first closable device adjacent the second end. The first closable device allows fluidic communication between an exterior of the first tubing and an interior of the first tubing in a first orientation of the vent valve, and blocks fluidic communication between the exterior of the first tubing and the interior of the first tubing in a second orientation of the vent valve.
