You want a hose rated safe for drinking water. It should have little metalized seal or tag on it says such.
Also those little white hoses let a lot of sunlight in and heat and little green and mostly brown stuff grows in it. A lined hose and one with silver in the lining, which I haven't looked for lately to help kill any nasties. Someone found aurethane hose that seems to fit the bill on the net, but not inexpensive.
