My experience with standard gallons of water is they tend to develop leaks. I've moved to a 55 gallon, food-grade, poly drum and three 7-gallon Aquatainers filled with water, thankfully because I have room for them.

I've had those leak, in the bathroom and on patio.
Both actual milk jug and distilled water jugs.
