The Hunter RZWS-36 Root Zone Watering System delivers efficient subsurface irrigation for trees and shrubs. Its patented StrataRoot™ internal baffles direct water, oxygen, and nutrients through the entire root zone to encourage deeper, stronger root growth while protecting irrigation hardware with an enclosed cylinder and protective grate.

  • 36-inch (91.4 cm) pre-assembled irrigation cylinder for subsurface installation.
  • Patented StrataRoot™ baffles distribute water evenly across root levels.
  • Compatible with ½" PVC via built-in Hunter swing joint; bubbler sold separately.
  • Pressure-compensating bubbler flow options: 0.9 L/min or 1.9 L/min; recommended pressure 1.0–4.8 bar (100–480 kPa).
  • Durable locking cap and grate offer vandal resistance; assembled in USA with 2‑year warranty.

RZWS-36 ships pre-assembled for fast installation and is serviceable from the top. Factory and field options include a check valve, reclaimed-water locking cap, and fabric sleeve for sandy soils.
