Abstract
An irrigation drip emitter, and methods relating to same, are provided for delivering irrigation water from a supply tube to an emitter outlet at a reduced and relatively constant flow rate. The emitter defining an inlet, outlet and flow passage extending between the inlet and outlet. In one form, the emitter includes a root growth inhibiting member disposed in the outlet of the emitter. In another form, the emitter includes stepped flippers for controlling fluid flow through the emitter. In yet another form, the emitter includes disconnected or freestanding outlet walls disposed in the outlet for preventing the outlet from collapsing under increased fluid line pressure without creating dead ends where grit can build-up. In other forms, the emitter defines one or more recess within which inserts may be disposed so the emitter and insert collectively define a fluid flow passage. Related methods are also disclosed herein.
