Abstract
An irrigation pipeline has a plurality of emitters equipped with discharge nipples for engagement by flexible hoses to release water at a trickle rate at selected subterranean locations within the radii of the hoses. A plurality of the nipples may be integral with a plastic manifold that is installed between confronting pipe ends and some of the nipples may be blind nipples that are sheared for activation of the emitters as required to meet increased demand for water.
