Part 1 is here, part 2 is here, and part 3 is here. The sad news is you can’t just fill those containers of water and forget about them for the next twenty-five years like you can with most of your dried food. Stored water needs to be changed out every six months. But don’t be discouraged; you’ve already bought all the stuff you need: containers, hose, and filter. That 7 gallon container has a handle for a reason. Just lug it back out to the yard, pour it out on the lawn or the garden, and fill it up again.
