It may seem hard to learn what you need to know about plumbing, but once you begin, you will see it is actually pretty straightforward.
To keep your pipes from getting frozen, never allow the temperature in your house to drop below freezing and insulate any pipes that are exposed to the elements. Your plumbing can freeze if the air around them fall below freezing. It could take some time for the pipes to thaw out so you can have water again. However, frozen pipes often burst, leading to flooding and costly repairs.
