Abstract

See full text

A method and a system for filling or passing a fluid through irrigation pipes equipped with dripping emitters having a non-return valve. The irrigation pipes are connected at one end to a container with the fluid and at the other end to an operable vacuum source such as vacuum pump. The vacuum source is operated to create vacuum in the pipes to suck the fluid from the container to fill the pipes. The fluid may be passed through the pipes to the vacuum source and then returned to the container by another pipe, or may be retained in the pipes without flow, or may be subjected to pressure pulses. In all cases, the non-return valves are plugged under the vacuum so as to prevent entry of external air or water into the pipes through the dripping emitters. A non pressure-compensated dripping emitter with built-in non-return valve is provided as well.
