What is the purpose of an anode in metallic water pipes?

• A. To connect the pipes to the main supply
• B. To mitigate corrosion and prolong the life of the pipes
• C. To facilitate the flow of water
• D. To monitor water quality

Answer: (B)

An anode in metallic water pipes serves the purpose of mitigating corrosion and prolonging the life of the pipes. This is crucial because metallic pipes, particularly those made of iron or steel, are susceptible to rust and corrosion when exposed to water and oxygen. The anode, often made of a more reactive material such as zinc or magnesium, is designed to corrode instead of the pipe itself. This sacrificial action helps protect the metal of the pipes from degradation, ensuring that the water distribution system remains intact and functional for a longer period. By investing in anodes, water systems can reduce maintenance costs, extend the lifespan of the infrastructure, and maintain the quality of the water being transported. This protective measure is essential in preserving the integrity of metallic systems, contributing to overall efficiency and safety in water distribution.
