Did a number on my water filtration system for the casa.
It'll do that to steel too. It's not uncommon here to see cast iron pump cases cracked open or even engine blocks cracked, if there was no antifreeze in the system.
It does strange things to oil too, if it gets cold enough. We just came out of a spell of -30 to -40 weather.
My truck was plugged in so it started, but it wouldn't move. The oil in the trans. was so cold it wouldn't engage the clutches. That's on an auto transmission.
After running for an hour it went into gear but when I went for a drive the wheals were frozen so the flat spot at the bottom stayed flat and it was like driving on square wheels.
Year ago I was running a water truck. One day when it was -40 I hit a two inch rubber hose with a hammer to break up ice inside, the dang hose broke in half.
Cold is a nasty thing if you are not prepared. I lost a brother to hypothermia on the warmest day of the winter, back in 1972.
