What Causes Burst Pipes? Alliance Ireland

Burst pipes can cause major flooding and damage problems for homeowners, which is why it is important to know what causes burst pipes and how they can be prevented. Below, we have outlined some of the most common causes of burst pipes, as well as what to do in a situation where your pipes have burst.


When water freezes in pipes due to cold temperatures, it expands and increases the pressure inside the pipe, as ice has greater volume than water. The built-up pressure needs to escape, causing it to burst through the pipe. We recommend turning on your faucets during extreme cold weather to allow a slow but steady stream of water to escape, keeping the water moving and preventing any pressure build-ups. We also recommend insulating your exposed water pipes and keeping the temperature in your home above 13 degrees.


If pipes are not secured, it is possible for them to move around inside the wall when water is suddenly turned on or off. The movement of the pipes can weaken the joints, eventually causing them to fail, thus allowing pressurised water to escape.


Water pressure needs to be maintained at normal levels to ensure your pipes are functioning properly, as increased water pressure can lead to burst pipes or a failed plumbing fixture. In most cases, normal pressure is 30-50psi and should not exceed 60psi. If your pressure is too high, our plumbers can install a pressure reducing valve, bringing it to a safe level.


Sometimes pipes can fail as a result of years of slow-building corrosion, with the most common cause being a pH imbalance in the water which can wear away at the iron.
