Copper pipes are known for their reliability and durability, but certain environmental and installation factors can lead to corrosion over time. Identifying and addressing these causes is crucial to maintaining the integrity of plumbing systems and ensuring the longevity of copper piping.
Low or High pH Levels in Water
Water with an imbalanced pH level can significantly impact the lifespan of copper pipes. Acidic water with a pH below 7.0 can accelerate corrosion by dissolving the metal, while highly alkaline water above 8.5 may cause scale build-up, weakening the pipes. Using high-quality components, such as copper pipe connectors from https://watkinspowis.co.uk/products/copper-pipe-fittings-and-press-systems/, can help mitigate some of these effects when paired with proper water treatment.
High Levels of Dissolved Oxygen
Excessive dissolved oxygen in water can lead to oxidative reactions with copper, causing gradual deterioration. This issue is common in systems with high water pressure or air pockets trapped in the pipes. Such conditions increase the risk of corrosion, particularly in areas where the water velocity is high.
Corrosion-Causing Bacteria
Certain bacteria, such as sulfate-reducing and iron bacteria, can contribute to the corrosion of copper pipes. These microorganisms produce acidic by-products that attack the metal, leading to pitting and weakening of the pipe structure. ScienceDirect explains what sulfate-reducing bacteria in more detail. Regular water testing and treatment can help reduce the presence of these bacteria and minimise the risk of corrosion in plumbing systems.
Improper Installation of Copper Piping
Improper installation practices, such as failing to deburr pipe ends or using excessive flux during soldering, can create weak points that accelerate corrosion. Ensuring correct installation methods and using high-quality products like copper pipe fittings and press systems can prevent these issues.
High Water Velocity and Sediment
Fast-moving water or the presence of sediment in pipes can cause hydraulic wear on copper piping, leading to thinning and eventual corrosion. This issue is especially common in systems with circulating pumps or pipes with an incorrect diameter.
Addressing common causes of copper pipe corrosion, including pH imbalances, bacteria and improper installation, is essential for maintaining efficient plumbing systems.
