A flat type pressure regulated drip emitter with a non-drain valve capabilities that is installable inside a water supply conduit during the conduit manufacturing process and characterized by that the emitters non-drain valve function is executed independently and separately from its pressure regulation function, through a portion of the emitters elastomer component that is strained and biased against the emitters water inlet opening and is moveable towards and away from an additional opening (additional to the emitters water outlet opening), exposed to the pressure prevailing in the emitters water exit pool and therefore, at any given time, this portion of the elastomer component is exposed to the maximum differential pressure that prevails in the system—on its one side to the water pressure prevailing in the water supply conduit and on its other (second) side—to the approximate atmospheric pressure.
