4. Setup and Installation

Follow these steps carefully to install the repair kit components into your Ames 2000B backflow preventer.

1. Preparation:
   • Shut off the main water supply upstream of the backflow preventer.
   • Open downstream valves or faucets to relieve pressure.
   • Drain any remaining water from the device.
   • Carefully remove the cover of the check valve assembly you intend to service (either 1st or 2nd check).
2. Component Removal:
   • Remove the old check disc assembly and spring. Note their orientation for reassembly.
   • Thoroughly clean the inside of the check valve body, removing any scale, debris, or old gasket material.
3. New Component Installation:
   • Apply a thin layer of approved lubricant (if provided or recommended) to new O-rings and gaskets.
   • Install the new spring into its designated position.
   • Carefully insert the new check disc assembly, ensuring it seats correctly and moves freely.
   • Replace any necessary gaskets or O-rings on the cover.
   • Reattach the cover, tightening fasteners evenly to ensure a proper seal. Do not overtighten.
4. System Restoration:
   • Slowly open the upstream shut-off valve to repressurize the system.
   • Check for any leaks around the repaired check valve.
   • Bleed any trapped air from the system by opening downstream faucets until water flows smoothly.

5. Operating Principles (Post-Repair)

After successful installation of the repair kit, the Ames 2000B backflow preventer should operate as designed. The check valves are designed to prevent the reverse flow of contaminated water into the potable water supply. The newly installed components ensure the check valve seals properly under normal flow conditions and closes tightly when backflow conditions occur. Regular testing by a certified backflow tester is required to ensure continued proper operation and compliance with local codes.

6. Maintenance

While the repair kit restores the functionality of the check valve, ongoing maintenance of the overall backflow prevention device is crucial for its longevity and effectiveness.

• Annual Testing: Backflow prevention devices, including those with repaired components, must be tested annually by a certified backflow prevention device tester. This is often a legal requirement.
• Visual Inspection: Periodically inspect the device for any signs of leaks, corrosion, or external damage.
• Environmental Protection: Protect the backflow preventer from freezing temperatures, which can cause significant damage. Consider insulation or removal during winter months if installed outdoors in cold climates.
• Component Replacement: If the device continues to malfunction after repair, or if other components show wear, consider a full device replacement or further professional servicing.
