Top 5 Causes of Bursting Pipes and How to Avoid Them

Plumbing pipes are essential to any home, providing water and sewage flow throughout the property. However, these pipes can wear down over time, often without our knowledge, even with regular use, until a leak or clog occurs. 

When a pipe bursts, it can cause severe property damage and loss. Here are our five top reasons for pipe failure and how to avoid them.

1. Freezing temperatures

If the temperature drops below freezing, water inside the pipe can freeze and expand, putting pressure on the walls until it eventually bursts. Improperly insulated pipes, such as those in unheated crawl spaces and attics or those that run parallel to poorly insulated external walls, are especially vulnerable to freezing. To prevent this, insulate exposed pipes and keep temperatures inside your home above freezing. 

2. Corrosion

Excessive and prolonged exposure to moisture and oxygen can cause metal pipes to corrode, weakening pipe walls, joints, and seals. This corrosion can create tiny cracks that expand over time, resulting in a complete rupture. 

To prevent this, regularly clean and inspect your pipes, use corrosion-resistant materials such as PVC or copper, and replace old and corroded pipes. Inspecting your pipes regularly for signs of corrosion, such as discolouration or warping, is essential. You must call a plumber to assess the situation if you spot these signs.

3. Clogs

Clogs can cause pressure to build up in the pipes, leading to a burst pipe if the pressure is too great. If a clog forms in your pipes, which causes water to build up, this can result in small leaks, leading to larger ones and, eventually, a complete rupture. 

Taking action quickly when a clog is present is essential to avoid costly repairs. Installing inexpensive mesh drain covers in showers, tubs, and sinks is a great preventive measure. Use strainers on your drains to catch hair and debris and a plunger to clean out clogs regularly. 

Additionally, water naturally contains minerals, and when magnesium and calcium are present in excessive amounts, they can accumulate and create what is known as hard water. 

Although generally safe to drink, hard water can cause issues with plumbing and appliances. Minerals can accumulate within pipes, causing a decrease in water flow and eventually damaging and weakening the pipes. 

The most effective way to prevent these problems is by installing a water treatment system that eliminates calcium and magnesium from the water.

4. High Water Pressure

High water pressure can strain your pipes, leading to a burst pipe. To prevent this, have a local plumber install a pressure regulator in your water system and inspect your pipes regularly to ensure they’re not overworked. 

5. Poor Installation

Burst pipes can be caused by improper installation, which can happen when those without the proper knowledge and experience attempt the job. Poor soldering or loose connections can easily lead to pipes bursting. Therefore, hiring a qualified local plumber to take care of any installation or repair work on pipes is essential.


Bursting pipes are a common plumbing issue due to cold weather, clogs, or old and worn-out pipes. To prevent bursting pipes, it is essential to keep an eye on any signs of wear and tear on your pipes, check for any clogs and blockages, and insulate your pipes to prevent them from freezing in cold weather. Additionally, regular maintenance and inspection of your pipes can help you identify any problems and take action before they become a more significant issue.
