Why do plumbers prefer using copper pipes in their installations?

Plumbers often prefer using copper pipes primarily due to their resistance to corrosion and excellent heat conduction properties. These characteristics make copper an ideal choice for water supply lines, especially in environments that can cause other materials to degrade over time. Copper pipes do not easily rust or corrode, which ensures a longer lifespan and minimizes the risk of leaks compared to other materials. Additionally, copper's ability to conduct heat efficiently allows for effective heating applications, such as in hot water systems or radiant heating, maintaining temperature better than many alternatives.

While factors like cost-effectiveness, ease of installation, and weight are relevant in the decision-making process, they do not provide the same level of durability and performance that copper pipes offer, making corrosion resistance and thermal conductivity the standout advantages for plumbers.
