It is the heat that the water has in it which is picked up underground.
Water pipes freezing underground.
To keep them insulated choose one of these two installation methods.
Both situations rely on electric heating cables but the similarities end there.
Freezing in a pipe creates a lot of pressure inside the pipe and can cause the pipe to burst and likely lead to serious flooding especially when there s no one around to turn off the water.
The ground is warmer below the frost line.
With a trickling faucet water with residual heat is kept flowing through the pipes.

Cold temperatures can cause water pipes to freeze.
When water freezes in your pipes whether due to quick drops in outside temperatures poor insulation or the thermostat set too low its volume expands and puts pressure on the pipe from inside.
This can cause a burst pipe but even a small crack or two can be the start of some devastating and expensive water and plumbing damage.
Up until recently a horse hair product was used.
Specialty insulation meant for underground water lines will prevent pipes from freezing.
Wire tie wire would be used to hold it in place.
