This invention relates to pulsating drip laterals for use in irrigation and other applications. The combination of pulsators and drip laterals is used for decreasing the flow of the drippers and for decreasing their chance of getting plugged. More specifically, this invention relates to pulsating drip laterals in which the pulsators are made so that pressurized fluid can flow through them while, at the same time, a low continuous flow of some of the fluid flows out from each pulsator at high intermittent pulsating flow to a group of drippers. It farther relates to pulsators that are connected in line of different types of drip conduit and to drip laterals in which pulsators are inserted in the drip conduits during the extrusion process of the conduits.
