Watermain breaks are more common during the winter months (November to March) because the low temperatures causes the soil to freeze and expand, resulting in frost loading or force applied to the pipe. External corrosion can cause pits to form in cast or ductile iron pipes, weakening them over time which could also cause a watermain to break.
