ABSTRACT:
A flushing valve for installation in a drip irrigation system comprises a head portion at one end of a tubular body that fits within the end of one of a series of lateral conduits of the system and has a recess open to the conduit. A transverse passage extends diametrically through the head portion to accommodate a flexible conduit which serves as a pilot line. When filled with fluid under pressure, the pilot conduit covers and seals a port between the recess of the tubular body and the transverse passage. An open slot is provided in the outer side of the head to facilitate installation of the pilot conduit.
