5 of 7 (Watch) Clean A Reverse Osmosis (RO) & Ice Line That Is Connected

This fifth part of the seven part series begins the reassembly of the RO filter system, having completed the sanitation of the RO filter in part one through part four. 

The sediment filter, the two carbon filters, the inline carbon filter and the RO membrane will be replaced with new ones.  The sediment filter removes large particles.  The two carbon filters conserve the thin film membrane by removing chloramines from the water.  The thin film membrane removes lead, PCBs, herbicides, pesticides etc. (about 97% of contaminants) from the water.  The in line carbon filter removes tastes and odors as the water flows from the storage tank to the RO faucet.

     RO filter disinfection instructions:

1. Reconnect the ice line to the refrigerator.
2. Turn off the feed water supply valve.
3. Turn off the storage tank ball valve.
4. Turn off the RO faucet.
5. Remove the inline carbon filter bypass tee.
6. Install a new line carbon filter.
7. Reconnect the storage tank tube to the tee on the input end of the inline carbon filter.
8. Disconnect the tubes from the RO membrane housing.
9. Install a new RO membrane in the RO membrane housing.
10. Reconnect the tubes to the RO membrane housing.
11. Position the RO membrane housing and the inline carbon filter back in the clips.
