I recently installed a small water fountain in my back yard and it requires distilled water to prevent stains. The problem is that it requires allot of water. I am looking for some kind of a filter system that will remove the salts from our water (San Diego Ca). I would also like to use this system to treat water for some salt sensitive plants. I recently saw that my neighbors have some kind of a pitcher in their refrigerator that treats small amounts of tap water. Will that work? Anyone have an idea. Thanks
