If you have acidic water, whether your copper is new or old you will get leaching and copper stains on the sinks and tubs and pinholes.
Copper stains? LOL. Just because it's red or orange in nature doesn't mean it came from the copper pipes.
What is a common by product of water and steel or water and iron that is an orange color in nature? (RUST)
You get rust whether you have copper or not. True copper stains tend to be green but typically these stains only remain on the outside of the copper pipe not on the interior that drains water into your sink or tub.
Pinholes can form because of dis-similar metals touching copper or weak solder joints that over time can wear due to vibrations or hammering of the water lines.
There are pros and cons to everything, but if you know and understand the properties of the metal you are working with in this case copper, it is one of the best metals to use with plumbing systems... even when you consider the costs of installation. When installation is done properly copper is the better choice in my opinion.

Copper stains are blue-green; they're copper oxides, not copper metal.

And they can occur because your water eats away at the pipe; they happen between joints, not at them.
Its odd that people would be worried about copper pipes when really high end pots and pans used for cooking food are made of copper, which is regarded as much safer than aluminum--which many people (not me) believe causes Alzheimers.
Too much copper is BAD For The Body. Yes copper water pipes cause many severe health issues.
This is a very old thread, but I could not pass. Had to say something
Then what pipes should you use from the following:
a. Plastic
b. Iron
c. Asbestos
Here are some choices: http://www.houselogic.com/home-advic...g-pipe-types/#.
And yes, old water mains were made with asbestos, and some of these have existed in a lot of places throughout the US. You just don't see them because they are buried deep under the streets.
If you are concerned about copper in your drinking water, then filter it. You can install an under sink RO or non-RO filter system.
