Abstract: A multichamber drip irrigation hose for distributing water and the like. A hose having a larger primary tube and a smaller secondary tube joined at a common wall, with passages in the common wall for flow from the primary tube to the secondary tube, and with passages in the secondary tube for flow from the secondary tube to the exterior. The tubes of the hose are formed from a strip of sheet material having opposite edges with one or both edges folded on itself to form a thicker edge, and with the strip folded and bonded to both thicker edges or one thicker edge and to the strip along a line spaced from the thicker edge, to form the primary and secondary tubes. Various fold configurations are possible.
