Rain Bird's Root Watering System (RWS) delivers water, oxygen and nutrients directly to the root systems of trees and shrubs, even in compacted soil.
The patented mesh basket allows underground installation to a depth of 91.4 inches for the RWS. The RWS is designed for use with water delivery components such as a bubbler head or dripper.
The RWS promotes tree and shrub investment protection, irrigation efficiency and landscape aesthetics through deep root growth and tree development.

Also compatible with Rainbird drip tube systems.

Features

Underground aeration and irrigation effectively prevents transplant shock to trees and shrubs. 
This High Efficiency tree irrigation solution provides up to 95% better distribution uniformity of water with minimal loss due to wind, evaporation or at edges.
With its unobtrusive design, the Underground Bubbler makes a lasting contribution to maintaining the natural appearance of a landscape.
In addition, the built-in locking device prevents vandalism when installed at ground level.

The 10.2 cm retaining cap and vandal-resistant locking device sit on a 91.4 cm semi-rigid perforated tube.
The SwingJoint connection, already attached, provides very good flexibility during installation.
