Hi When water freezes, it increases in volume about 9%. The ice then shrinks
as the temperature decreases. The shrinkage is tiny, about 0.4% going from 30F to -50F. So either remove 9 percent of the water or leave out a plug so when it expands it has somewhere to escape from.

It is long past time to exchange the contents for fresh water. My wife wishes they were not in the furnace room because at least one of them restricts access to shelving there. The only other places they could go are in the garage or the shed. We live in Utah near Salt Lake City and the water will freeze during the winter in any unheated location. In fact, our fall and spring seasons have many freezing night and warm days giving us a repeated freeze and thaw cycle for days at a time. Do any of you have experience with these barrels, and will freezing them make them break? If not a problem, how much head room should there be to allow the water to expand as it freezes? Thanks for any feedback. [Non-text portions of this message have been removed] [Non-text portions of this message have been removed]
