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

This fourth part of the seven part series rinses the bleach water out of the RO filter system through the RO faucet, through the ice line to the refrigerator and through the drain line from the membrane housing.  The bleach must be rinsed away to eliminate the taste and smell of bleach. 

The RO filter system used in this demonstration is a 5-stage system which uses a thin film RO membrane.  Bleach is destructive to thin film RO membranes and must be rinsed from the RO system before putting a new RO membrane in the RO membrane housing.

This fourth part of the seven part series completes the sanitation of the RO filter system and the ice line to the refrigerator.

     RO filter disinfection instructions:

1. Turn on the ball valve at the refrigerator end of the ice line and drain all of the bleach water out of the storage tank.
2. Turn on the storage tank ball valve, turn off the RO faucet, and turn off the ball valve at the refrigerator end of the ice line.
3. Turn on the feed water supply valve to the RO filter.
4. Fill the storage tank with fresh water.
5. Turn on the RO faucet.
6. Turn on the ball valve at the refrigerator end of the ice line.
7. Run water through the RO faucet and the ball valve at the end of the refrigerator until the storage tank is about half full.
8. When the storage tank is about half full, turn off the feed water supply valve to the RO filter and finish draining the storage tank through the RO faucet and the ice line.
