Copper pipe corrosion can occur for various reasons, and addressing the underlying causes is essential to prevent further damage and costly repairs.
Look at your water quality
The quality of the water flowing through the pipes plays a role in corrosion. High levels of acidity or alkalinity, as well as the presence of certain minerals and contaminants, can contribute to corrosion. For example, acidic water can corrode copper pipes over time.
Chlorine can be corrosive to pipes
Chlorine is commonly added to drinking water, but it can be corrosive to copper pipes. Long-term exposure to high levels of chlorine can lead to corrosion.
Is your water hard?
Hard water contains high levels of minerals, particularly calcium and magnesium. The minerals in hard water can form deposits on the interior of copper pipes, leading to corrosion. This is known as scale build-up.
Dissimilar metals can cause issues
When copper pipes encounter dissimilar metals in the plumbing system, it can lead to corrosion. This occurs when there is an electrical current between the metals, causing corrosion at the point of contact.
According to PBC Today, copper pipe can provide a fire-safe and sustainable alternative in projects. If you require a supply of copper pipe, specialist outlets such as watkinspowis.co.uk/products/copper-pipe-fittings-and-press-systems are on hand to advise.
Microbiologically Influenced Corrosion (MIC) can occur
Microorganisms in the water can contribute to corrosion. MIC occurs when bacteria or other microorganisms form colonies on the interior of the pipes, leading to corrosion. This type of corrosion is more common in stagnant areas of the plumbing system.
Improper installation practices can cause problems
Poor installation, such as inadequate support for pipes or improper pipe sizing, can contribute to corrosion. Incorrect installation can lead to uneven stress on the pipes and it can create conditions that accelerate corrosion.
