    Tips: Swing Check Valve Leakage Troubleshooting

    One of the most common problems with swing check valves is leakage, which can occur due to wear and tear of the sealing components, improper installation, or damage to the valve. To troubleshoot this issue, inspect the valve for any visible signs of damage, such as cracks or corrosion, and replace any damaged parts. Check the valve's seating surface and ensure that it is clean and free from debris. Also, make sure that the valve is installed correctly and tightened to the proper torque.
