How to fill out double check valve backflow

1. Start by locating the double check valve backflow preventer. It is typically installed near the main water supply or where the water line enters a building.
2. Ensure that the valve is in the closed position before proceeding with the filling process.
3. Connect a hose to the appropriate inlet on the backflow preventer. This inlet is usually marked with an arrow indicating the direction of water flow.
4. Place the other end of the hose into a clean water source, such as a faucet or a bucket filled with water.
5. Open the valve on the clean water source to allow water to flow into the backflow preventer. The pressure from the incoming water will cause the check valves inside the device to open.
6. Monitor the pressure gauge on the backflow preventer to ensure that it is within the acceptable range. If the pressure is too high, you may need to adjust the flow of water from the clean water source.
7. Once the pressure is stable and within the acceptable range, close the valve on the clean water source.
8. Slowly open the valve on the backflow preventer to release any trapped air or debris. This will help ensure proper functioning of the device.
9. Inspect the backflow preventer for any leaks or signs of damage. If any issues are found, consult a professional for repairs or replacement.
10. Finally, make sure to inform the relevant authorities or water regulatory agencies about the successful filling of the double check valve backflow preventer.
