Yeah Cecil I had it freeze up once, last winter I would start it up sometimes when the temps would stay above 10 degrees, and one night it dropped to 2 below and it froze, but it thawed that afternoon when it got into the 30's.
I elevated the pipe so it would have a continuous even downhill slope so that there wouldn't be any air pockets to reduce flow, but being elevated doesn't let it get insulated by the snow pack.
The weather station showed 7 degrees up there this morning but the stream water was 37 degrees 3 days ago so it should still be flowing. Atleast I have the insulated line and pump putting water to the pond.
