A flow-regulating drip emitter, comprising a base that includes an inlet connector configured for connection to an upstream line with a water source and a cover attached to the base, the cover including an outlet connector configured for connection to a downstream line. At least one of the cover or the base defines at least a first labyrinth passageway having a first resistance to water flow and a second labyrinth passageway having a second resistance to water flow different from the first resistance to water flow and further wherein the base and the cover are structured so that movement of the cover in relation to the base connects the inlet connector to the outlet connector via only the first labyrinth passageway, and wherein further movement of the cover in relation to the base connects the inlet connector to the outlet connector via only the second labyrinth passageway.
