How to Change RO Housing and Membrane?
1. Begin by turning off the feed water supply line valve to the RO system, as well as the valve on the water tank.
2. Open the RO faucet, allowing the system's pressure to safely dissipate.
3. Carefully remove the blue safety clip, push down the collet, and disconnect the tubing from the membrane housing.
4. Utilize the wrench to carefully unscrew and remove the membrane housing cap.
5. With pliers, extract the used membrane, discard it, and insert the new one. Ensure the end with the two small washers is inserted first, pushing it until it clicks securely into place.
6. Tighten the membrane housing cap securely, reconnect the tubing, and reattach the blue safety clip for a firm seal.
Note: If the housing cap does not screw on easily, gently twist the RO membrane until it aligns correctly with the pure water outlet.
