What is a common use for copper piping in plumbing?

Copper piping is commonly used for water supply lines due to its excellent durability and resistance to corrosion. This material allows for the safe transport of potable water and has a proven track record in plumbing applications. Copper has a high central tensile strength, making it suitable for high-pressure systems, and it resists scaling and biofilm formation, which can improve water quality.

In addition to its mechanical properties, copper also has antimicrobial properties, which can help in reducing the growth of harmful bacteria within the plumbing system. Its flexibility allows it to be easily formed and joined through various methods, such as soldering or brazing, which contributes to its efficiency in installation.

This makes it the preferred choice for residential and commercial water supply systems, further emphasizing its relevance. Other options, although relevant in specific contexts, do not represent the primary or most common use of copper piping in plumbing.
