If you live in an area with extreme winter temperature fluctuations like we do in Calgary and area, you run the risk of the pipes in your home freezing. As the water running through your pipes begins to freeze, it will expand 10% in volume until the pressure rises enough to split your pipes open, potentially causing severe water damage to your home. Preventing pipes from freezing in the first place is always the priority. However, should you discover your pipes have frozen, there are techniques that you can use to avoid a leak and potential damage to your home.
