I am confused about the frost line and how it affects my concern for frozen pipes at the cabin. I would like to open the cabin this spring and am worried that I have to blow out the lines each time I leave on the weekend. I will leave the temperature inside that cabin at 45 degrees to prevent any internal pipes from freezing. What I am not sure of is:
The pump is in the cabin.
The cabin has a crawl space with no basement.
The well is about 100 ft away from the house in a shed.
There is a check valve in the house between the pump and the line in from the well.
When there is no water running and the pump is not turned on, does the water on the well side of the check valve flow back into the well?
Does this mean the water line that travels through the frost line is empty and I never have to worry about any freezing in the crawl space or within the frost line?
Why was it that the plumber never had to blow the line back toward the well when they winterized the cabin? Does gravity take the water back to the well? Assuming there is a grade downward toward the well?
Thanks! Im just concerned about frozen lines, especially underground.
