- 2-Port Manifold with Unions: Designed for impact and UV resistant construction.
- Heavy-Duty In-Line Valve: Engineered for easy installation and maintenance, providing professional-grade performance.
- Speed-Seal™: Facilitates weather-proof wiring connections.
- PVC Slip Adapters: For use with ¾-inch PVC pipe or 1-inch PVC pipe using a 1-inch coupler.
Installation Steps
- Prepare the Location: Dig a trench and prepare a valve box base if installing underground.
- Connect to Mainline: Attach the manifold to your irrigation mainline. The manifold features special swivel unions for a secure, watertight seal.
- Connect to Zone Pipes: Attach the manifold to your PVC or poly zone pipes using appropriate adapters. Ensure all connections are hand-tightened to prevent leaks.
- Wiring: Connect the valve solenoids to your sprinkler timer using the Speed-Seal™ wiring system. Label wires for easy identification.

Operating Instructions
The Orbit 57250 manifold uses L-Series valves with internal-bleed, 24 VAC solenoids. These are compatible with most standard irrigation controllers, including those from Orbit and Hydro-Rain.
- Automatic Operation: Connect the solenoids to your irrigation timer. Program your timer according to its specific instructions to control the watering schedules for each zone.
- Manual Operation: Each valve typically includes a manual override lever or screw. Refer to the specific valve's markings for manual ON/OFF operation. This allows for testing or temporary watering without the timer.
Maintenance
The design of the Orbit preassembled manifold prioritizes ease of maintenance. The swivel unions allow for simple replacement or addition of components.
- Valve Replacement: If a valve needs replacement, unthread the swivel union, slide it back, and replace the valve. This process avoids extensive digging or re-gluing.
- Adding Components: Additional manifold fittings, such as drip filters or pressure regulators, can be easily integrated into the system using the swivel unions.
- Preventative Measures: To ensure a watertight seal and prolong the life of your manifold, consider applying Teflon tape to all threaded connections (excluding solenoid threads) and lubricating O-rings during installation or maintenance.

Troubleshooting
If you encounter issues with your Orbit 57250 manifold, consider the following common troubleshooting steps:
- Leaks:
- Check all connections for proper tightening. Hand-tighten swivel unions.
- Ensure O-rings are properly seated and lubricated.
- Inspect valve bodies for cracks or damage.
- If leaks persist, consider disassembling and reassembling connections with fresh Teflon tape.
- Valve Not Opening/Closing:
- Verify electrical connections to the solenoid are secure and correctly wired to the timer.
- Test the solenoid by manually operating the valve. If manual operation works but automatic does not, the solenoid or wiring may be faulty.
- Ensure sufficient water pressure.
- Water Flow Issues:
- Check for blockages in the pipes or valves.
- Ensure the main water supply to the irrigation system is fully open.
