What can i use to store water that is safe to use. I will be bringing about 5 gallons a day home and need to store it until i get the tank up and ready. I know that some store it in a large garbage can. Can i Do this safely. If so how long can it be stored and will it go bad. It is RO/DI water. I will not have the tank ready for a few weeks but wanted to get the water home. If i do store it will it require some type of circulation??
