How to Re-Pressurize Your Reverse Osmosis (RO) Tank – A Comprehensive Guide

Introduction to RO Tank Re-Pressurization

　　Maintaining the optimal pressure in your RO tank is crucial for efficient operation. This guide will walk you through the steps to re-pressurize your RO tank, ensuring it functions at its best. Follow these instructions carefully to achieve the desired results.

Step-by-Step Guide to Re-Pressurizing Your RO Tank

　　Step 1: Turn Off Feed Water Supply

　　Before you begin, it’s essential to turn off the feed water supply to your RO system. This prevents any water from entering the tank during the re-pressurization process.

　　Step 2: Drain the Tank

　　Next, drain the old tank completely. Use the spigot to remove all the water from the tank. This step ensures that you start with an empty tank, making the re-pressurization process more effective.

　　Step 3: Close the Tank Valve

　　Locate the tank valve, which is marked as point Y in Figure 1. Close the valve securely to prevent any air from escaping during the re-pressurization process.

　　Step 4: Disconnect the Yellow Line

　　Find the yellow line connected to the tank valve. Carefully disconnect it from the valve to prepare for reconnection after re-pressurization.

　　Step 5: Locate the Pressure Valve

　　Under the blue cap on the tank, you’ll find the pressure valve. This is where you will measure and adjust the pressure.

　　Step 6: Measure Current Pressure

　　Use a pressure gauge to determine the current pressure in the tank. This step is crucial to know how much pressure needs to be added.

　　Step 7: Re-Pressurize the Tank

　　For a 4-gallon tank, use an air compressor or bicycle pump to re-pressurize it to 5 psi. For a 14-gallon tank, set the pressure to 7 psi. Ensure the pressure is evenly distributed throughout the tank.

　　Step 8: Reconnect the Yellow Line

　　After re-pressurizing the tank, reconnect the yellow line to its original position at point Y. This completes the re-pressurization process.

Key Points to Remember

  • Always turn off the feed water supply before starting the process.
  • Ensure the tank is completely drained to avoid any water interference.
  • Use the correct pressure settings for your specific tank size.
  • Double-check all connections after re-pressurization.

Troubleshooting Common Issues

　　If you encounter any issues during the re-pressurization process, refer to the following tips:

　　Low Pressure Issues

  • Check for any leaks in the system.
  • Ensure the tank valve is fully closed.
  • Use a higher-quality air compressor or pump.

　　High Pressure Issues

  • Adjust the pressure settings accordingly.
  • Inspect the pressure gauge for accuracy.
  • Consider replacing the pressure valve if it’s malfunctioning.

Conclusion

　　Re-pressurizing your RO tank is a straightforward process that can significantly improve the efficiency of your RO system. By following these detailed steps, you can ensure your tank operates at the optimal pressure. Remember to turn off the feed water supply, drain the tank, and carefully follow the re-pressurization steps. Regular maintenance will extend the lifespan of your RO system and provide you with clean, pure water.
