Copper-alloy tubing must be supported every how many feet when placed horizontally?

Copper-alloy tubing, when installed horizontally, must be adequately supported to prevent sagging, ensure structural integrity, and maintain proper flow within the tubing. The standard practice is to provide support at intervals not exceeding 8 feet for horizontal runs of copper-alloy tubing. This spacing helps mitigate stress on the joints and fittings, minimizes the risk of damage, and ensures that the tubing remains in the correct position for efficient operation. Following this guideline is essential for compliance with plumbing codes and best practice standards in mechanical systems.
