Safety Information
Always follow local plumbing codes and regulations during installation and maintenance. Ensure proper personal protective equipment (PPE) is used. Depressurize the system before any service or repair. Do not exceed the maximum working pressure of 175 Psi.
Setup and Installation
Installation should be performed by a qualified professional in accordance with all applicable local and national plumbing codes.
- Pre-Installation Check: Inspect the valve for any signs of damage during shipping. Ensure all components are present.
- System Preparation: Flush the upstream piping thoroughly to remove any debris that could damage the valve.
- Orientation: Install the valve in the correct flow direction as indicated by the arrow on the valve body. The valve must be installed horizontally.
- Connections: Use appropriate pipe thread sealant on NPT connections. Tighten connections securely but do not overtighten.
- Support: Provide adequate support for the valve and associated piping to prevent strain on the connections.
- Testing: After installation, slowly pressurize the system and check for leaks. Perform a backflow prevention device test as required by local codes.
Operating Instructions
The Febco 850U-QT features quarter-turn shutoff valves for easy operation.
- Opening the Valve: Turn the blue handles of the quarter-turn shutoff valves so they are parallel with the pipe. This allows water to flow through the assembly.
- Closing the Valve: Turn the blue handles of the quarter-turn shutoff valves so they are perpendicular to the pipe. This stops water flow through the assembly.
- Test Cocks: The four test cocks (small brass fittings with screws) are used by certified testers to verify the proper operation of the check valves. Do not tamper with these unless performing a test.
Maintenance
Regular maintenance and testing are crucial for the proper functioning and longevity of the backflow preventer.
- Annual Testing: This device must be tested annually by a certified backflow prevention device tester to ensure it is functioning correctly and providing the required protection.
- Winterization: In climates where freezing temperatures occur, the valve must be drained or protected from freezing to prevent damage. Consult local codes for specific winterization procedures.
- Inspection: Periodically inspect the valve for any visible signs of leaks, corrosion, or damage.
- Repair: Repairs should only be performed by qualified personnel using genuine Febco replacement parts.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Water leaking from test cocks | Debris in check valve, worn O-rings, or faulty check valve. | Flush the system. If problem persists, have a certified technician inspect and repair/replace internal components. |
| Reduced flow downstream | Partially closed shutoff valves, debris in the valve, or a faulty check valve. | Ensure shutoff valves are fully open. Flush the system. If problem persists, professional inspection is required. |
| Visible external leaks | Loose connections, damaged valve body, or worn seals. | Check and tighten connections. If valve body is damaged, replacement is necessary. For worn seals, professional repair is recommended. |
