How to Change RO Housing and Membrane?
1. Begin by turning off both the feed water supply line valve to your RO system and the valve on the water tank.
2. Open the RO faucet to let the system's pressure decrease.
3. Detach the tubing from the membrane housing by removing the blue safety clip, then pressing down the collect and pushing it out.
4. Utilize the wrench to unscrew and remove the membrane housing cap.
5. With the assistance of pliers, remove the old membrane and replace it with the new one. Ensure the end with two small washers is inserted first and firmly seated within the housing.
6. Securely replace the membrane housing cap, reconnect the tubing, and restore the blue safety clip to its position.
Note: Should the housing cap resist fitting back easily, gently twist the RO membrane for proper alignment with the pure water outlet.
