We’re holding our breath here this morning at Wild Ozark, waiting to see what happens when the lines on the mountain thaw.
See, we’d insulated all the lines under the house and figured, hey, it shouldn’t freeze now under there tonight – let’s see what happens. Well, we forgot about the nature of still water in cold weather. If we didn’t leave a tap open, the water would no longer be flowing anywhere in our lines… it would become still.
And it did what still water does.
Now we most likely have a solid line of ice in the lines all the way from the tank at the top down to the house at the bottom.
The other natural thing that water does when it freezes is expands.
That’s why those little ice shards are lifting rocks. Because it’s expanding. But the thing about those shards is that it expands upwards because there’s nothing standing in the way except the weight of that little rock. To the sides of whatever little puddle of water froze, there is the surrounding earth keeping it contained, and that earth is stronger than the freezing water. Inside a water line, the thing standing in the way is the wall of the water line. And the ice is usually stronger than the plastic used to hold that water, especially when the plastic has been exposed to sunlight for a few years, causing it to become less flexible.
We don’t get our water from a well or a municipal water tower in the area. Our water comes from a spring about 500 yards above us on the mountain behind our house. It’s held in a 1500 gallon tank about 300 yards above the house on the mountain below the spring. This arrangement comes with a bit more maintenance than you’d find in most set ups. Keeping it flowing during winter is critical.
So, when it all thaws out I’ll take a little hike up the mountain to see what I find. This has happened once or twice before in the last 10 or so years. It’s always a spectacular show. I’ll bring the camera with me, just in case.
The Verdict
Update at 1144: Whoo-hooo! We got lucky. No leaks. I did bring the camera though and took some photos of the spring and cave out that way. Couldn’t get too close to the cave because the rocks I would have had to cross were slippery with ice and algae. I’ll post those when I get a chance later and leave the link here for you.
