Thanks for all the replies. I think for now I will stick to my Aqua Liters for portability (fires and stuck on the highway).<br><br>So, the conclusion, is for home use and being stuck inside (earthquakes, riots, floods, whatever) the 2.5 gallon or 1 gallon containers from the supermarket are okay so long as I change them? Do I need new containers or can I just refill the bottle?<br><br>The 1 gallon are like big plastic milk jugs and the 2.5 gallon ones are the ones with the handle and the spigot (?) on the bottom pointing down. I'll probably get a dozen of them to have a month's supply of water.<br><br>I will probably keep them in big Rubbermaid storage bins under my bed, will that be safe? It's cold, dark and should be dry (Southern Cali)
