Rain Bird A22425 Root Watering System 0.25 Gpm 36 in

Product Description

The RAIN BIRD A22425 is a subsurface root watering system designed to deliver water directly to the root zone of trees and large shrubs. Built with an integrated check valve, the unit prevents backflow and siphoning that can contaminate the supply line. At 0.25 gallons per minute (GPM) flow rate and 36 inches in length, this system places moisture where it is needed most — deep in the soil profile rather than at the surface. Licensed irrigation professionals and landscape contractors install this type of device in both residential and light commercial planting applications.

The A22425 is suited for deep-root irrigation of established trees, newly transplanted specimens, and large ornamental shrubs where surface drip or spray irrigation does not reach the full root zone. The 36-inch tube length allows installation into compacted or clay-heavy soils where root systems extend well below grade. This system supports water-efficient irrigation programs that aim to reduce surface runoff and evaporation loss.

Key Features

• 36-inch length positions water delivery deep within the root zone
• 0.25 GPM flow rate provides controlled, low-volume water delivery
• Integrated check valve prevents backflow and supply line contamination
• Designed for subsurface installation to minimize surface evaporation and runoff
• Compatible with standard irrigation system connections for straightforward integration

Compatibility

Designed as an OEM-style component for subsurface drip and root watering irrigation systems. Consult the irrigation system layout and local water authority requirements to confirm fitment before installation.

Installation Notes

Installation should be performed by a licensed irrigation contractor in accordance with local plumbing and irrigation codes. Shut off the irrigation system supply and relieve line pressure before connecting or disconnecting any components. Use appropriate soil augers or installation tools to seat the 36-inch tube to full depth without stressing the check valve assembly. Verify that the check valve orientation follows the direction of flow as marked on the unit before backfilling.
