Water from the lake in the winter

[DanP]

I'm thinking of converting the cottage to a year round residence and I'm interested if anyone has experience with a self draining water system like this one... https://www.cottagewatersupply.com/w...water-systems/

I know I could always run a heat-line water pipe but think a drainback would be more efficient (if it works). I'm also getting tired of fighting and replacing the jet pump every few years and a submerged pump looks appealing. Digging a well is not an option as I would not be able to bury the lines given my topography and a railroad track.

I'd also be adding a multi-stage filtration and UV light as well (lots of good advice on the forums for this topic).

Thoughts? Recommended installers?

Thanks.
