The Science Behind Freezing Water and Pipe Damage

The science of why water causes pipes to burst when it freezes is rooted in a basic physical principle: water expands upon freezing. When water turns into ice, its volume increases by about 9%. This expansion exerts significant pressure inside the pipes. Most pipes, especially those in sprinkler systems, are not designed to withstand such pressure. Consequently, the expanding ice pushes against the pipe walls. If the pressure becomes too great, it can lead to cracks or even burst the pipe. This issue is particularly problematic in sprinkler systems, as they often have numerous sections and joints susceptible to damage. Understanding this scientific basis highlights the importance of thoroughly removing water from sprinkler systems before the onset of freezing temperatures to prevent costly and inconvenient damage.
