What Causes Water Mains to Leak?
If you are experiencing a leaking or burst water main, identifying the underlying cause is essential to prevent further damage. Our engineers carry out detailed assessments to repair the fault and implement long-term solutions that reduce the risk of repeat failures.
Some of the most common causes of water main leaks include:
1. Pipe Age and Materials
Older water mains are more susceptible to deterioration, particularly those installed before the 1980s. Many historic systems used cast iron, which, while once standard, lacks the flexibility of modern materials. Over time, thermal movement and corrosion can cause cracking and leakage.
2. Changes in Water Pressure
Sudden or sustained increases in water pressure can place excessive stress on water mains. If pressure exceeds design limits, pipes may crack, leak, or rupture entirely, potentially causing flooding, structural damage, and increased water charges.
3. Excavation Damage
Groundworks carried out by contractors or property owners can accidentally strike underground water mains. Contact from machinery or hand tools can fracture pipes, leading to leaks or complete failure.
4. Temperature Extremes
Fluctuating temperatures can significantly affect underground water mains. In cold conditions, freezing ground expands and applies pressure to buried pipes, while thawing causes contraction. In warmer weather, soil shrinkage and movement can also stress pipework. Repeated thermal cycles increase the likelihood of cracking or bursting, making proactive maintenance essential.
5. Heavy Vehicle Loading
Water mains installed at shallow depths are vulnerable to damage from heavy vehicles. The weight and vibration from traffic can compact surrounding soil, deform pipes, or disturb alignment—particularly where pipes are already weakened by age or corrosion. Regular inspections beneath high-traffic areas help reduce the risk of failure.
