Many people do not believe you can use an reverse osmosis system for your fridge, but all you do is use a “T” adapter and run an extra line to your fridge. This is what I have done, and it works great. I got my system from Aquasafe Systems at http://www.aquasafecanada.com and they set me up with everything I needed, and told me how to set it up this way so I have the pure water to both my tap, and fridge.
