Now is the time to become more about plumbing. You might have wanted to learn these skills before, but just never set the time aside to do so.
To prevent pipes from freezing, maintain a constant temperature in your home above freezing, and be certain to adequately insulate those pipes that are out in the weather. Your pipes 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, your pipes can explode, leading to flooding and costly repairs.
