Hello all, I'm looking for some basic water storage info. I had previously been using bottled gallons that come in three packs but rotating them is a pain and I don't like the idea of plastics leeching chemicals into the water over the long term. I've picked up a few 6 Gallon storage jugs that I plan to simply fill with tap water. How often should the containers be emptied and refreshed? Is it advisable to sanitize the container after each emptying, or only necessary upon initial filling? What is the recommended method of sanitizing my jugs? Thanks all!
