What is a C11000 copper pipe?
A C11000 copper pipe is a type of copper water tube made from Electrolytic Tough Pitch (ETP) Copper, which is at least 99.90% pure copper. It is the most common and widely used copper pipe for plumbing and heating systems in residential, commercial, and industrial applications. When you see a shiny, new copper pipe in a hardware store or a plumbing installation, it is most likely C11000.
