Abstract
A pop-up emitter comprising a base defining a circular bore along a central axis. The base further defines a circular opening at a distal end of the bore. A hub is provided, defining an aperture, positioned in the center of the opening. A circular cap is provided, sized to fit inside the opening, the cap including a spike extending perpendicular to the cap from the center of the cap. The spike resides movably within the aperture such that the cap is movable between a closed condition in which the opening is closed, and an open condition in which the opening is open.
