An irrigation system is disclosed which includes a source of fluid under pressure which can be supplied by a pump or from domestic water sources and a system of irrigation pipes which contain a plurality of pressure vessels, the system of irrigation line being controlled by valves. Each of the pressure tanks is connected to the irrigation line by an inlet port containing a check valve means and each of the pressure tanks has an outlet port which is controlled by a diaphragm-type valve, the operator inside of which is connected to the irrigation line. The irrigation line is controlled in such a manner that the tank alternately builds up pressure and the line is reduced in pressure to atmospheric permitting the tank to discharge.
