The Rain Bird RWSBC1401 is a subsurface Root Watering System designed to deliver water, oxygen, and nutrients directly to the root zone of trees and shrubs. Its durable basket-weave canister installs below grade to bypass compacted soil and encourage deep root development. 36 in. semi-rigid mesh tube topped by a 4 in. vandal-resistant retaining cap and locking grate for secure, below-grade installation. Factory-installed 1401 bubbler on a fixed riser (0.25 gpm) provides consistent subsurface delivery and simple connection to lateral lines. Built-in check valve prevents line drainage (approx. 10 ft. holdback), reducing maintenance and minimizing water loss between cycles. Optional sand sock accessory for sandy soils stabilizes media and improves emission uniformity where needed. Integrated grate collar clip accepts 1/4 in. tubing for quick hookups; 1/2 in. M NPT inlet on the swing assembly for standard connections. Aesthetically unobtrusive below-grade design protects hardscape, deters vandalism, and promotes faster, healthier root establishment. Ideal for new plantings, transplanting, and long-term tree care, the RWSBC1401 improves irrigation efficiency by directing water to the root ball, reducing evaporation and runoff. See manufacturer installation guides and technical sheets for placement, flow requirements, and detailed specifications before installation.
