ABSTRACT:
An irrigation leakage prevention device for coupling between an irrigation supply source and an irrigation emitter unit. The device comprises a tubular throughflow conduit, at least the central portion thereof being formed of a resiliently flexible material and having end portions which are held against resilient displacement, a central barrier member being fixedly located within the conduit. With a water supply pressure less than a predetermined minimum, the central portion of the conduit sealingly embraces the barrier so as to prevent throughflow and when the water supply pressure exceeds this minimum, the central portion is resiliently displaced away from the barrier so as to allow throughflow.
