Preparation for Repair

1. Isolate the Backflow Preventer: Close the upstream and downstream shut-off valves to isolate the backflow preventer from the main water supply.
2. Depressurize the System: Open the test cocks on the backflow preventer to relieve any trapped pressure within the device. Ensure all water has drained.
3. Gather Tools: Have appropriate wrenches, screwdrivers, and a clean work surface ready.

First Check Repair Procedure

Follow these steps carefully to replace the first check components:

1. Remove Access Cover: Carefully unbolt or unscrew the access cover for the first check valve assembly. Note the orientation of the cover and any gaskets.
2. Extract Old Components: Remove the existing first check disc, spring, and any other internal components. Inspect the valve body for any debris or damage.
3. Clean Valve Body: Thoroughly clean the interior of the valve body where the first check assembly sits. Remove any scale, dirt, or old gasket material.
4. Install New Components: Using the new parts from the repair kit, carefully install the new spring, disc, and any associated seals. Ensure all components are seated correctly and in the proper orientation. Refer to the original assembly for guidance if necessary.
5. Replace Gasket and Cover: Install a new gasket (if provided) and reattach the access cover. Tighten bolts or screws evenly to ensure a watertight seal. Do not overtighten.

Post-Installation Check

1. Slowly Restore Water Supply: Gradually open the upstream shut-off valve to allow water to re-enter the backflow preventer.
2. Purge Air: Slowly open the downstream shut-off valve and any downstream fixtures to purge air from the system.
3. Inspect for Leaks: Carefully check all repaired areas for any signs of leaks.
4. Test Functionality: It is recommended to have the backflow preventer tested by a certified technician after any repair to ensure it is functioning correctly and meeting all regulatory requirements.

Maintenance

Regular maintenance and inspection are crucial for the reliable operation of your backflow preventer. While this kit provides replacement parts for the first check, the overall device should be:

• Inspected annually by a certified backflow technician.
• Protected from freezing temperatures.
• Kept free from debris and obstructions.

Troubleshooting

If issues arise after installing the repair kit, consider the following:

• Continuous Drip/Leak from Test Cock: This may indicate that the first check valve is not seating properly. Re-check installation of the disc and spring for correct orientation and ensure no debris is preventing a seal.
• Water Hammer: If water hammer occurs after repair, ensure air has been fully purged from the system.
• Visible Leaks from Cover: Indicates an improper seal. Ensure the gasket is correctly seated and the cover bolts are tightened evenly.

For persistent issues, contact a qualified plumbing professional.
