Corrosion in Copper Pipes

Copper pipes are commonly used in modern properties and can be an ideal solution when water properties align with the material. However, corrosion becomes problematic under specific conditions. Key preconditions for copper corrosion include soft water with insufficient limescale to form a protective calcium carbonate layer, pH values that are too high or low, stagnant water where oxygen reacts with copper to form copper oxide, and foreign metal particles that create galvanic corrosion.

Prevention strategies using Merus Technology involve installing a Merus Ring at the main water inlet to decompose existing limescale incrustations, keep oxygen dissolved to reduce corrosion in stagnant water, and alter chemical conditions in soft water to prevent corrosion. The technology works by changing pipe conditions to interfere with chemical processes and form a thin protective layer along pipe walls. A particle filter at the main inlet may also be recommended to prevent metal particles from entering the system. The effects become visible through changes in water color and limescale deposits in fixtures.
