Big Muddy rancher wrote::help: The over flow line from my spring comes from the spring cribbing down to the trough. In the real cold weather the trough froze over and the line froze back up to the cribbing and now I have no overflow. I can get to the bottom of the line as it is open but can't get the ice up the hill to melt out. I tried using my truck exhaust but that hardly touched it.. Any ideas?
Get a small hose long enougth to go the distance and fit it to a backpack weedsprayer filled with hot water and push it through the line.
Guys at the local plumbing shop unthaw lines like this all the time.
I unthawed my waterlines to my outdoor boiler with the same small hose attached to a garden hose.Worked real fast.
