According to CDA spokesman Ken Geremia, "The vast majority of homeowners depend on copper to stay cool, warm and refreshed. What many people don't realize is that indoor plumbing, as we know it, began with copper here in the United States some 75 years ago, and it's still the most dependable material used for transporting water."

If you've got a plumbing system or are currently servicing one that fits CDA's description, the association would like to hear about it. Send the information (and photos, if possible) by regular mail or email to:
