Burst pipes can happen for several reasons, and knowing the main causes can help you avoid future issues. Here are the most common reasons for burst pipes:   Freezing Weather: In cold conditions, water in your pipes can freeze and expand, which causes the pipe to crack or burst. This is especially common during winter.   Pipe Corrosion: Older pipes can corrode over time, especially if made of metal. This weakens the pipe walls, making them prone to bursting.   Excessive Water Pressure: When the water pressure in your pipes is too high, it can create stress that eventually leads to the pipes bursting.   Tree Roots: Sometimes, tree roots grow into underground pipes, blocking or damaging them, which can lead to bursts.
