Common Causes of Burst Water Pipes

Bursting water pipes is a common issue that homeowners face. While water supply pipes are built to withstand force, they can still burst due to significant structural damage. Here are some common causes of burst pipes.

Tree Roots

As trees grow, their roots spread, probing the soil for sustenance. In their quest for moisture, these roots can infiltrate and encroach upon underground water pipes. The roots exert pressure on the lines, seeking entry into the tiny cracks or weak points in the pipe's structure.

The constant pressure exerted by the roots weakens the structural integrity of the pipes, making them susceptible to cracks and fractures. Over time, the roots can penetrate the pipe walls, causing them to burst.

Implementing protective measures, such as installing root barriers or choosing pipe materials resistant to root intrusion, can mitigate the risk. Timely detection and proper management of tree roots near water pipes are also crucial in avoiding the disruptive consequences of burst pipes and the subsequent water damage.

Frozen Water in the Pipes

When water freezes inside the pipes, it undergoes a phase change from liquid to solid, increasing in volume. The pressure from the expanding ice can exceed the structural strength of the pipe, causing it to burst. 

The burst typically occurs in areas where the ice blockage is present, as the pressure builds up in those sections. Consequently, the sudden release of tension can result in significant water damage to the surrounding area. Insulating pipes, allowing faucets to drip to maintain water flow, and keeping indoor temperatures above freezing can help prevent freezing and subsequent bursting.

Weak Pipes

Water flows through pipes with a certain pressure level, which is necessary to ensure the smooth transportation of water from one place to another. However, weak pipes are unable to withstand this pressure effectively. 

As the water flows through the pipes, the weak spots in the pipe structure are subjected to excessive stress. Over time, these weak areas start to deteriorate, forming small cracks or fissures.

When the cracks develop, the pressure from the water intensifies these vulnerabilities. The force exerted by the water pushes against the weakened areas, causing the cracks to expand further. Eventually, the weakened sections of the pipes can no longer bear the strain, leading to a burst pipe.

Install strong pipes to prevent bursting. 

Wear and Tear

With regular use, pipes are subjected to constant pressure and movement, causing them to undergo wear and tear. This continuous stress weakens the structural integrity of the pipes over time. 

As the pipes weaken, the pressure the flowing water exerts becomes more pronounced. The weakened areas of the pipes eventually reach a breaking point, unable to withstand the force. This results in a burst pipe, where water forcefully escapes from the compromised section.

Replacing worn-out or damaged pipes on time helps maintain the overall integrity of the water supply system.

Underground Movements

Seismic activity like earthquakes unleash powerful waves that propagate through the Earth's crust. These waves cause the ground to shake vigorously, subjecting the buried water pipes to intense stress. As a result, the pipes experience strain, potentially leading to cracks or fractures.

Construction work, particularly large-scale excavations or tunneling projects, can also disrupt the stability of the ground. Heavy machinery and digging activities disturb the soil and underlying layers, causing the ground to shift. This shifting can apply excessive pressure on the water pipes, weakening them over time and eventually causing them to rupture.

Contractors should take caution to secure pipes during construction work.
