>If I kept home-filled bottles around in there that long they would get gunky. If the bottles are clean, and the water is clean, the water will not get "gunky". I have a few 20L water containers at home for emergencies. I sanitized the containers and filled them with chlorinated tap water. A few years after I filled them, while I was moving, the water was still fresh tasting and clear.
