What is the maximum interval for supporting horizontal 1 1/2" copper pipe?

The maximum interval for supporting horizontal 1 1/2" copper pipe is 12 feet. This requirement is aligned with industry standards, which dictate that copper pipes must be adequately supported to prevent sagging and ensure a proper flow of water through the system.

When pipes are not supported at appropriate intervals, they can experience undue stress, potential bending, or damage, which can lead to leaks or system failure. The 12-foot interval ensures structural integrity, making certain that the pipes remain secure and aligned throughout their length. Proper support is particularly important for horizontal pipes, as they rely on gravity for drainage and flow, and adequate spacing helps to minimize movement that could result from thermal expansion or vibration.

This standard is established by plumbing codes to enhance both the longevity of the piping system and overall safety in plumbing installations.
