Abstract
A pop-up irrigation device for use in a low pressure irrigation device is described. The device has a housing, a riser partially extensible from the housing and a nozzle body removably attached to an end of the riser in a non-threaded manner, such as using a snap-fit. One, two or more connection tubes or ports may extend laterally from the housing and can each be configured to be connectable to flexible irrigation tubing. An annular cap can be attached to the open end of the housing and may include an annular, radially-inward extending seal. The closed end of the housing may include a depending stake with a plurality of blades to facilitate mounting of the housing relative to the ground.
