The Hunter RZWS-18 Root Zone Watering System delivers efficient subsurface irrigation for young trees and shrubs. Its patented StrataRoot™ baffle system directs water, oxygen, and nutrients throughout the root zone to encourage deep, healthy root growth while protecting irrigation hardware with a durable, locking cap. The pre-assembled unit simplifies installation and reduces on-site labor.

  • Patented StrataRoot™ internal baffles distribute water evenly through the root zone and add structural rigidity.
  • 18-inch (45 cm) enclosed irrigation cylinder with locking cap for vandal resistance and long-term protection.
  • Ships without a bubbler or swing joint—designed for subsurface delivery; bubbler and check-valve variants available in other models.
  • Compatible user options include a fabric sleeve (RZWS-SLEEVE) to prevent soil intrusion and replacement caps (P/N 913300SP/913301SP).
  • Pre-assembled design reduces install time; suitable for residential and commercial tree and shrub irrigation projects.

Backed by Hunter's product documentation and a two-year warranty, the RZWS-18 is a reliable choice for targeted, high-efficiency irrigation. See product cutsheets and installation guides for CAD files, spec details, and recommended installation practices.
