Komponenter inkluderet

This comprehensive repair kit includes the following genuine Watts components:

• Dæk O-ring
• To sæder
• Seat O-rings
• Disc assemblies (for both first and second checks)

Opsætning og installation

This repair kit is designed for the servicing of Watts 007M2 Series Double Check Valve Assemblies. Installation involves replacing the internal components of the existing valve. It is recommended that installation be performed by a qualified professional or an individual with experience in plumbing and backflow prevention systems.

1. Forberedelse: Ensure the water supply to the backflow assembly is shut off and the system is depressurized before beginning any work.
2. Demontering: Carefully disassemble the existing 007M2 double check valve assembly according to the original manufacturer's instructions or standard plumbing practices. Note the orientation and placement of all components.
3. Udskiftning af komponenter: Replace the old internal components (O-rings, seats, disc assemblies, springs, check cages) with the new, genuine Watts parts provided in this RK 007M2-T kit. Ensure all new O-rings are properly seated and lubricated if necessary.
4. Genmontering: Reassemble the double check valve assembly, ensuring all parts are correctly aligned and tightened to the manufacturer's specifications. No special tools are required for servicing these components.
5. Test: After reassembly, slowly restore water pressure to the system and carefully check for any leaks. It is highly recommended to have the backflow assembly tested by a certified backflow tester to ensure it meets all local codes and operates correctly.

For detailed visual instructions, refer to the original Watts 007M2 Series Double Check Valve Assembly manual or consult a professional.

Operating Principles (of the Repaired Valve)

Once the Watts 007M2 Double Check Valve Assembly is repaired with this kit, it will function as designed to prevent backflow. A double check valve assembly consists of two independently operating check valves, installed in series. This design provides protection against backpressure and backsiphonage in non-health hazard applications.

• Normal Flow: During normal water flow, both check valves are open, allowing water to pass through.
• Backpressure Prevention: If downstream pressure exceeds upstream pressure, the check valves close, preventing contaminated water from flowing back into the potable water supply.
• Backsiphonage Prevention: If upstream pressure drops (e.g., due to a main break), creating a vacuum, the check valves close to prevent siphonage of downstream water back into the supply.

The integrity of these internal components, replaced by this kit, is crucial for the reliable operation of the backflow preventer.

Opretholdelse

The RK 007M2-T kit itself is a maintenance product. Regular maintenance of backflow prevention devices is critical to ensure their proper function and compliance with local regulations. This kit facilitates the necessary internal component replacement that is part of routine maintenance or repair when components show signs of wear or failure.

• Årlig test: Backflow prevention assemblies, including those repaired with this kit, typically require annual testing by a certified backflow tester to ensure they are operating within specifications.
• Komponentinspektion: During testing or any servicing, inspect all internal components for wear, cracks, or deformation. Replace any damaged parts promptly using genuine Watts repair kits.
• Miljøbeskyttelse: Protect the backflow assembly from freezing temperatures and physical damage, which can compromise its integrity and lead to component failure.

Fejlfinding

This repair kit addresses common internal component failures in the Watts 007M2 Double Check Valve Assembly. If your backflow preventer is exhibiting issues, consider the following:

• Constant Leakage from Relief Valve: This often indicates a problem with the first check valve or a fouled relief valve. Replacing the disc assemblies and O-rings in the first check can resolve this.
• Failure to Hold Pressure: If the assembly fails its annual test, particularly if one or both checks are not holding pressure, it's a strong indicator that the internal components (seats, discs, springs) are worn or damaged and require replacement.
• Reduceret flow: While less common for internal component failure, significant debris accumulation can reduce flow. Ensure the system is flushed before and after repair.
• Synlig skade: Inspect the exterior and interior components for cracks, corrosion, or other physical damage.

Always consult a certified backflow technician for diagnosis and repair if you are unsure about the cause of a malfunction or the repair process.
