What is the horizontal support requirement for copper pipes smaller than 1 1/2 inches?

For copper pipes smaller than 1 1/2 inches, the horizontal support requirement is 6 feet or closer. This standard ensures proper support and protection against sagging, which can lead to issues such as stress on the joints, leaks, and reduced flow over time. Adequate support minimizes the risk of damage due to weight and thermal expansion, maintaining the integrity and longevity of the plumbing system. This guideline is crucial for installers to follow to comply with plumbing codes and standards, as well as for maintaining efficient and safe plumbing practices.
