Abstract
A drain fitting for use in an irrigation system for draining water from the irrigation system, regardless of pipe size in the irrigation system, generally includes a grip portion and a neck coupled to the grip portion. The neck defines a first engagement portion having a first diameter, for coupling the drain fitting to a pipe of the irrigation system having a diameter corresponding to the first diameter of the first engagement portion, and a second engagement portion having a second diameter, different from the first diameter, for coupling the drain fitting to a pipe of the irrigation system having a diameter corresponding to the second diameter of the second engagement portion.
