Abstract: This invention concerns a liquid distribution system consisting of modular elements fitted with two or more outlets. Each modular element (1) has an external jacket (2) through which one or more tubular ducts (3) pass, each receiving two opposed stopcocks or control valves (15) connecting or shutting off the branch pipes (4) from the internal ports (9, 10) through which the liquid flows, these inner ports (9, 10) being fitted with a projection (12) and recess (11) fitting for assembly of the various elements so as to form the distribution system, the branch pipes (4) being fitted with a spike base (27) to be inserted into the flower pot or into the flower bed, the system permitting the obtaining of a perfect and homogeneous distribution of the liquid at a minimum pressure, low costs, limited space requirements and easy installation.
