We currently draw water from the lake with a jet pump for the summer cabin. Ditching the jet pump for submersible next spring. Plan on keeping cabin water seasonal but want to be able to have water in new building when we go up in winter.

Old neighbor had in line heat cable that could freeze in the line without being damaged then thaw line in half hour or so after they would get there and plug it in. They did this several times a year. The “Heat line” brand is crazy expensive, but they say its ok to freeze. I know the neighbor didn’t have that brand years ago.

If anyone uses an in line heat cable that’s able to freeze/thaw without damage I’d appreciate knowing the brand. Need aprox 250’

They make a valve that lets the water go back into the well so the water line totally drained. You wont find a commercial one but talk to a plumber because by code your not suppose let water go back into the aquifer. I know alot of cabins here in Minnesota do this in the winter. Or just dont put a check valve on the top of the submersible pump. But by doing this you will get air in your line everytime you pump kicks in always.

Thanks Reaperman.

I know the bleeder valve you’re talking about. It opens when it senses low pressure. When you turn pump off and draining pressure tank it opens. The problem is it only drains to the water level of the lake so where the poly pipe goes through the ice it would still have water in it. Same problem with no check valve, it only drains to water level. Works ok from well but not so much in a lake.

I have a drain-back valve installed in the well casing at my camp. But you're right Trapset, that won't work for your situation. I hope you get some answers.
