The Rain Bird RWSB1402 Root Watering System delivers targeted subsurface irrigation and aeration for shrubs and small trees. Its 36 in semi-rigid mesh tube and factory-installed 1402 bubbler place water directly at the root zone to reduce transplant shock and conserve water.

  • 36 in (91.4 cm) tube: semi-rigid mesh canister with 4 in (10.2 cm) retaining cap and vandal-resistant locking grate.
  • 1402 micro-bubbler: factory-installed on a fixed riser — 0.5 gpm (≈1.9 L/min) flow rate for efficient root watering.
  • Inlet & connections: 1/2 in MPT inlet and factory swing assembly for easy lateral line installation; grate collar includes clip for 1/4 in tubing.
  • Optional accessories: sand sock for sandy soils and check valve option to prevent line drainage.
  • Benefits: minimizes evaporation and runoff, promotes deeper root growth, and helps stabilize young plants.

Designed for below-grade installation so the top grate sits at grade, the RWSB1402 is ideal when you need reliable, low-profile irrigation that protects landscapes and hardscapes. See the included technical documents and installation instructions for site-specific guidance, recommended connection details, and spacing guidelines. Compatible with standard drip and bubbler supplies.

Routine visual inspection and occasional flushing of the emitter are recommended to maintain performance. Use the optional accessories for sandy soils or to prevent line drainage where needed.
