Key Features:

Type: SB-TEE Link T
Pressure Rating: Suitable for high-pressure applications up to 5.5 bar.
Compatibility: Designed for use with SB + SPX-FLEX flexible mounting systems.
Application: Ideal for connecting sprinklers or diffusers in areas requiring flexible installation.

Setup and Installation

Proper installation of the Rain Bird A46004 Link T is crucial for a leak-free and efficient irrigation system. Follow these general guidelines:

System Preparation: Ensure the main irrigation line is depressurized and drained before beginning installation.
Component Connection:
- Connect the main irrigation line to one end of the T-link.
- Connect the flexible SB + SPX-FLEX tubing to the other two ends of the T-link. Ensure all connections are secure and tight to prevent leaks.
Sprinkler/Diffuser Attachment: Attach your chosen sprinkler or diffuser to the flexible tubing. The flexibility of the SB + SPX-FLEX system allows for precise positioning.
Leak Check: Once all connections are made, slowly repressurize the irrigation system and carefully inspect all connections for any signs of leakage. Tighten connections as necessary.

Note: For specific instructions regarding the SB + SPX-FLEX system or your particular sprinkler/diffuser, refer to their respective manuals.

Operation

The Rain Bird A46004 Link T is a passive component within your irrigation system. Its primary function is to provide a secure and flexible connection point for water distribution to sprinklers or diffusers. Once installed correctly, it operates as an integral part of the water delivery network.

Ensure the overall irrigation system is operating within its designed pressure range (up to 5.5 bar for this component).
Regularly monitor the system during operation for any unusual water flow or pressure drops, which could indicate a leak or blockage.

Maintenance

Minimal maintenance is required for the Rain Bird A46004 Link T, but periodic checks can help ensure its long-term reliability:

Visual Inspection: Periodically inspect the T-link and its connections for any visible signs of wear, cracks, or damage, especially after seasonal changes or ground disturbance.
Leak Detection: During irrigation cycles, check for any water pooling around the T-link connections, which may indicate a leak. Tighten connections or replace seals if necessary.
Cleaning: If the T-link is exposed to soil or debris, gently clean it to prevent accumulation that could affect its integrity or surrounding components.
Winterization: In regions subject to freezing temperatures, ensure the entire irrigation system, including the T-link, is properly drained and winterized according to standard irrigation practices to prevent freeze damage.

Troubleshooting

Most issues related to the A46004 Link T are typically associated with installation or external factors. Here are some common problems and their solutions:

Problem	Possible Cause	Solution
Water Leakage at Connection Points	Loose connection Damaged O-ring or seal Incorrectly sized tubing	Tighten connections securely. Inspect and replace any damaged seals. Ensure tubing matches the T-link's specifications.
Low Water Pressure at Sprinkler	Partial blockage in the T-link or tubing System-wide pressure issue	Inspect the T-link and tubing for debris; clear any blockages. Check the main water supply and other system components for pressure issues.
Physical Damage to T-link	Impact from vehicles or machinery Freeze damage UV degradation (less common for buried components)	Replace the damaged T-link. Ensure proper winterization procedures are followed. Consider protective measures for exposed components.
