It's also a required element so I guess a question might be how many micrograms of copper are consumed per day by using a copper lined bottle. Adults should get 900 micrograms daily unless they are also consuming a lot of zinc and then one must do more math. Gastric bypass surgery is thought to be a risk factor for copper deficiency. Usage of proton pump inhibitors may also contribute to copper deficiency by reducing the ability of the body to absorb dietary copper.

Most homes have copper water pipes. That's probably more important to test as corrosion in water bottles should be easy to spot. There are test kits one can buy to test their water at home.

Most new construction in the last 10 years is all PVC and PEX, not copper.

My home was built in 1970. Most homes in my area were built in the 70's and 80's. When I rebuild my home I do plan to use PEX. I also want to use the ManaBloc port adapters because that was a damn cool idea whoever came up with it. Then I will just have to worry about chemicals leeching into the water such as MTBE and tert-Butyl alcohol unofficially of course but I don't drink from the well water anyway.

My plumber prefers copper pipes. He's replaced a couple of leaks (in PVC pipes) with copper at core junctions in my house. I never knew it was dangerous.

Copper is also more expensive, more showy, and probably easier to manipulate. But what it provides more benefit for the plumber is not necessarily the best for the client.
