Question: Will Shutting Off Water Keep Pipes From Freezing?

When should I be worried about pipes freezing?

The Minimum Temperature to Keep Pipes From Freezing Depending on their exposure to wind and the elements, pipes can freeze when temperatures are higher than 20 degrees.

Why is it dangerous for your pipes to freeze?

What causes pipes to freeze and burst?
