The pump is self priming. Somehow the water below the lake level does not freeze, as the line between the pump and the lake is buried in the ground. It's a pretty simple set up. When you turn the pump on you can actually hear the air hissing out of the valves.
The only thing we have to do manually is pour RV antifreeze down the drains so that the water in the traps do not freeze.
