Does copper tubing used for plumbing (water lines) have antibacterial properties?

Hi Alice:

Copper metal and therefore copper tubing does indeed have "inherent antibacterial properties"... it is used in many applications for exactly that reason.

Copper properties and uses. Introduction.

It is the anti-bacterial nature of copper that makes it a great material for use as a water supply. The newer thermoplastic pipe manufacturers (pex pipes) are working to create antibacterial linings to mimic the properties of copper.

Let us know if need anything else...
