Water pipes from wells are supposed to be buried below the frost line, probably 6' in northern Wisconsin. If the house was originally built as a summer retreat, then the lines are probably not that deep.

Yes, Salti - I was just confirming the OP's suspicions. The only way to fix this is to reinstall the water lines, which means digging a trench below 6' down. There maybe some well installers who can somehow "push" a pipe through the soil. How far is the well from the house?

Let's get a few basics covered:

1. Do you think the line is freezing or do you know for certain?
2. Describe the setup at the well - are there unprotected lines?
3. Is the pump running and no water, or is the pump not trying to run?
4. If the pump is not running, have you checked the breaker?
5. If the pump is running, is it a jet pump?
6. Before the weather turned cold, did you experience low water flow?

Three feet of the pipe is exposed in the crawl space. I agree with the other comments that the buried line outside the cabin doesn't appear to be six feet down. The cabin was originally built to be a three season home, two years ago we remodeled and added a furnace.

Do you think having a heated pipe on the inside would help with the buried pipe on the outside of the cabin? Not sure how far the well is from the crawl space.

To answer the last question: I am confident that the line is freezing as the pump is working and tries to draw water. Did not notice a lower water flow in the late fall.

Does anyone have an opinion on how easy it would be to lower the pipe myself?

Not particularly easy but just a lot of work. How long is the pipe? Where does it come out of the well? Is the pump in the well> Hopefully, it comes out of the well casing several feet below the surface. You would have to dig down to that point, and then trench it all the way to where it comes up from the crawl space into the house.

No, warming the pipes inside is not going to unfreeze the underground pipes.

What is the distance between the well and the pump? Have you ensured the pump is primed?

Who says the pipe is frozen underground and not above ground?

Not the OP, she said, " It seems like the pipe going through going to the well seems To be freezing up..."

If you can access each end of the pipe hook a welder to it to thaw. If the pipe does not have sharp angle (elbows) you can run a hose thru it with steam to thaw. Both will work. Call some plumbers that have been in business for awhile for assistance.

Metal pipe?

Will call a plumber. Thanks for all the suggestions/comments.
