How to Change RO Housing and Membrane?
1. Ensure safety first by turning off the feed water supply line valve to the RO system, along with the water tank valve.
2. Next, open the RO faucet to let the system pressure release completely.
3. For disconnection, remove the blue safety clip, press down the collect, and gently push out the tubing from the membrane housing.
4. Utilize the wrench to carefully remove the membrane housing cap.
5. With pliers, extract the used membrane and replace it with a new one, inserting the end with two washers first. Push it until it securely seats within the membrane housing.
6. Reattach and secure the membrane housing cap. Reconnect the tubing and restore the blue safety clip to its rightful place.
Note: If the housing cap resists easy replacement, gently twist the RO membrane to ensure it aligns correctly with the pure water outlet.
