Josh, Saw your comment about water. I was taught that water freezes at 32 degrees but goes through a morph around 26 degrees where it expands dramatically in a one time shock event. That's when water pipes burst. The expansion is a shock load to copper pipes which will fish mouth open at a weak spot, usually in the sidewall of tubing, rarely in a fitting. Steel pipes behave differently usually pushing out a weaker cast fitting. My understanding is that as the temperature lowers, the ice does not expand any further. Is that about right or is there more to it?
