The Rain Bird RWS-S-B 1401 Root Watering Bubbler provides targeted subsurface irrigation that delivers water, oxygen, and nutrients directly to the root zone of trees and shrubs. Its compact shrub-sized configuration is intended to supplement surface irrigation, reduce runoff, and encourage deeper, healthier root development for newly planted or established landscape specimens. Compact 10" (25.4 cm) delivery tube designed for localized subsurface placement, positioning the bubbler where roots can access moisture and reducing evaporation from the surface. 0.25 gpm (0.95 l/m) bubbler on a riser provides slow, controlled discharge ideal for deep watering without disturbing soil or causing excess runoff. Includes a 2" snap-on cap and base to secure the assembly at grade while allowing easy access for inspection, adjustment, or replacement. 1/2" M NPT inlet spiral barb elbow connects to common irrigation tubing and fittings for straightforward integration with existing drip or bubbler systems. Patented basket-weave canister supports ground installation to the RWS-S depth and protects the delivery tube; intended use includes bubbler heads and drip emitters for flexible irrigation options. Installation depth for the RWS-S model is up to 10" (25.4 cm); the RWS and RWS-M variants support deeper placements (18" and 36" respectively). Refer to the included installation tips, instruction manuals, technical specification and site reports for detailed placement guidance, troubleshooting, and maintenance recommendations to ensure reliable, long-lasting performance in landscape and renovation projects.
