tweva, given the climate here, it would be a backhoe level project to put the lines deep enough to stay below the frost line in the winter, and the lines would need to terminate in the house for the same freezing reason. I’d as well have to have the line going deep enough in the pond to stay below the ice level. The part that doesn’t freeze is on the far side of the pond relative to the house. I do have a hand pump on my well for drinking water and that’s a shorter walk to the house than the pond but I figured it would be less effort to grab bucketfuls from the pond for the toilets. I’d find out real fast if that’s true or not.
