Copper water tube systems have had a long and successful application history. On rare occasions, however, there have been failures due to aggressive water, defective workmanship, inappropriate materials selection, or improper system design or operation.

This paper describes proper materials selection, system design and operations, correct workmanship practices and effective water treatment alternatives to prevent corrosion, while complying fully with the 1991 Lead-Copper Rule Amendment of the 1974 Safe Drinking Water Act.
