Deliver water across all levels of the root zone for high-efficiency subsurface irrigation of trees and shrubs.

All Product Videos

Features

Operation

AIR FLOW

For young plants and trees to thrive, they must receive adequate irrigation and a steady exchange of oxygen across all levels of the root zone. This encourages roots to grow deep and remain safely below ground, allowing plants to become strong and fully established. Developed to meet this challenge, the Root Zone Watering System features Hunter’s patented StrataRoot™ design, a series of internal baffles that direct water, oxygen, and nutrients to the root zone and provide rigidity to the irrigation cylinder for added durability. The RZWS comes preassembled for easy installation, and the enclosed design and grate protect irrigation hardware from vandalism. For efficient irrigation of trees and shrubs delivered throughout the root zone, the Hunter RZWS is the optimal solution.

Key Benefits

Patented StrataRoot™ baffles divert water to all levels of the root zone while adding strength to the unit
Durable locking cap for vandal resistance
Pressure-compensating bubbler for accurate water flow
Built-in Hunter Swing Joint for direct installation to ½" PVC fitting
Preassembled for fast installation
