I have three, 7 gallon jugs of
water. The jugs were from the camping section at walmart. I can’t remember how old that water is, but I wouldn't want to drink it. It’s at least five years old. Can I just dump it and refill or do I need to clean or sanitize? I’m thinking it would be best to put a little bleach in for a day or two then rinse? How much bleach?
