Since water will be flowing through the pipes when the temperature gets low there will be a great possibility for it to freeze inside the pipes clogging it. It is imperative to ensure that the water works in the house are in top condition lest it will lead to the daily routine of the house will go for a toss.
I too had this problem during one of the winters which made the entire household works lag. This lag also affected the office and school timings for the kids and us. In many of my neighbor’s houses the ice caused the pipes to crack leading to several plumbing related problems.
I realized that not all houses had this issue in the neighborhood. When enquired with them I found out that they had their plumbing done through the walls, this was a fabulous idea and hence I went about changing it in my house that summer. You will do well to remember that in spite of your best efforts at protecting such damage, where the temperature hits a new low, the condensation of water in the pipes might lead to cracking of the walls in some cases.
The leaks due to this problem will make the entire room wet and untidy. Hence, I always attend such plumbing problems immediately as more the delay, more we will suffer. Gutters are another place where there will water freezing. If proper researches are done about these problems on the internet, one can find accurate solutions and precautions to be taken and can deal with it accordingly.
