What type of piping is generally used for potable water in residential plumbing?

Copper piping is widely recognized for its use in residential plumbing systems, particularly for transporting potable water. Its popularity stems from several key benefits. It is durable and can withstand high temperatures and pressures, making it suitable for both hot and cold water applications. Additionally, copper has natural antimicrobial properties, which can help maintain the water's quality by preventing the growth of bacteria within the piping.

Furthermore, copper pipes are resistant to corrosion, which contributes to their longevity in plumbing systems. They can also be joined using various methods, including soldering, which creates strong, watertight connections. This makes copper a reliable choice for ensuring clean and safe drinking water for households.

While other materials like PEX and PVC are also frequently used in plumbing, copper remains a preferred option for many plumbers when it comes to installations involving potable water due to its proven track record and reliability. Galvanized steel, while once common in plumbing, is now less desirable for potable water due to issues such as rusting and the potential for lead contamination.
