Pipe got disconnected last night near water source. I reconnected but no water flows. Pipes are full of ice in places at temp below freezing. Nothing has burst. And no risk of water damage to house. I have a drain at house so most water would have gone out the drain during the night rather than sit in pipes. Current temp is minus 6C. Temp will be getting above freezing in next few days. I assume if the water is connected it will work its way down and create some friction. 2 inch PVC pipe is about 700 ft completely exposed to elements.
