What to Do About Burst Pipes in Interior Walls

 
Causes of Burst Pipes Due to Extreme Temperatures
 

One of the most common reasons for burst pipes is exposure to extreme temperatures. When water freezes, it expands. This expansion puts immense pressure on the pipe walls, especially if the pipes are made of older or weaker materials. The constant cycle of freezing and thawing can weaken the pipe over time, eventually causing it to burst. In regions with sharp temperature drops, the risk is higher.

 
Age and Material Degradation
 

Pipes that have been in service for many years may begin to show signs of deterioration. Over time, factors like corrosion, buildup of minerals, and constant exposure to water can lead to the degradation of the pipe material. The weakened structure may not handle the water pressure as effectively as it once did, which can result in a burst. Age and poor-quality materials are significant contributors to this issue.

 
Faulty Installation and Poor Quality Materials
 

If pipes are not installed correctly, or if substandard materials are used, they can become vulnerable to bursting. Improper joining of the pipes, inadequate support, or fast-changing water pressures can lead to leaks and eventual bursts. Even a minor defect in the installation process can develop into a major problem over time.

 
Increased Water Pressure
 

Sudden increases in water pressure can stress pipes beyond their capacity. When water flows too forcefully through pipes that are not designed for high pressure, they may start to crack or burst. A spike in water pressure might occur due to a malfunctioning pressure regulator or excessive demand on the system.

 
Water Hammer and Sudden Pressure Shocks
 

Water hammer refers to the shock wave that forms when a valve shuts off abruptly. This phenomenon creates pressure surges that can be harmful to pipes, especially if they are already weakened by age or material fatigue. These shock waves accumulate stress within the system, sometimes leading to a pipe burst over time.

 
Soil Movement and External Impacts
 

Pipes buried underground are subject to forces outside their control. Natural ground movement, soil erosion, or even heavy traffic overhead can shift the pipes. This movement, particularly in areas with unstable soil, can bend or break the pipes, causing a burst.

 
Chemical Corrosion from Water Quality Issues
 

Certain water conditions can accelerate the corrosion process. The presence of chemicals, salt, or byproducts from disinfection processes may weaken metal pipes over time. This type of corrosion compromises the pipe structure and may eventually lead to a burst.

 
Energy and Vibration Stress
 

Everyday vibrations caused by nearby construction, heavy machinery, or even ongoing traffic can add stress to a plumbing system. In older homes or commercial buildings, these continuous vibrations might contribute to the weakening and eventual bursting of pipes. While the effect is often subtle, over time it can be significant.

 
Combined Effects in Diverse Regions
 

Many factors can play together, making it difficult to pinpoint a single cause for burst pipes. For example, in our work with projects located in St. Louis and Nashville, we see that a mix of aging infrastructure, temperature extremes, and installation issues often combine to create the problem. Understanding the interplay between these factors is key to assessing why pipes might fail.

• Extreme temperature changes causing water to freeze and expand
• Degradation of older materials due to corrosion and mineral buildup
• Faulty installation leading to vulnerabilities
• Sudden increases in water pressure and water hammer effects
• Soil movement and external physical impacts
• Chemical corrosion from water quality issues
• Continuous vibration and stress over time
