Reverse Osmosis for Refrigerators

Reverse Osmosis for Refrigerators

After installing my Watts RO Pure systems I decided it would be nice to hook it up to my refrigerator. First thing I did was buy the Watts Ice Maker Kit but I bought the wrong size. Once I had all the parts, I realized it would be easier and cheaper to just buy the parts individually. It seems the majority of the cost is the tubing and if your refrigerator came with and ice maker, it probably already came with the tubing.

I have read some horror stories about RO systems flooding kitchens and ruining wood floors. That said, my instruction do not follow the recommendation made by Watts. You should use caution and check your setup for leaks for the first 24hrs. The ball valve I received from Watts was defective and leaked after about 15 minutes once the pressure built up in the tank.

These direction assume the tube from your refrigerator is 1/4 inch. If you have something different you will need a different ball valve and possibly an adapter.
