Although most of my DHW & CH installation is made of copper pipes, I have noticed that the mains water pipe coming into my house as well as a few other pipes are of a uniform dark brown color (no it's not paint).
Is this aging copper or could it be some other material like lead? The house was built in the 50s.
Cheers...
