I have one of those walter filtration systems with three tanks under my kitchen sink. The water comes out of a special faucet in the sink. I've noticed that barely any water now comes out of the special faucet for it. Also the ice maker in the refrigerator, which I think is somehow linked to it, is barely making ice. Does anyone know what's going on. Do I need to get new filters for the system, or is the system just broken? Will I need a professional, or can I do it myself. Also I just noticed that there is a large blue "tank" under the sink - is this somehow connnected and could this be the problem?
Thanks for any help.
