We have been getting flakes in our water. We've replace the filter and checked the water line from the house. Everything is good. It appears that the flakes are from the plastic tubing that is coiled in the based of the refrigertaor (behind the crisper drawer). I can get a replacement kit for the water tubing, but I am wondering if I'll have to replace it every year, or so. I know this used to be a problem with tank type resevoirs for water, but I thought the tubing was supposed to fix it. Any susggestions?
