Vertical copper pipe 1 1/2 inch and larger shall be supported at what intervals?

Supporting vertical copper pipe properly is crucial for maintaining the integrity and functionality of plumbing systems. For pipes that are 1 1/2 inches in diameter and larger, the requirement to support them at each story ensures that the weight and stress of the pipe, particularly when filled with water, do not lead to sagging or bending. This support helps prevent damage to the pipe as well as potential leaks at joints or fittings.

By requiring support at each story, it accommodates for the vertical height and the potential for dynamic loads, such as water flow and pressure changes. It is also important for ensuring safety and compliance with building codes that are designed to protect the structural integrity of both the plumbing system and the building itself. Supporting pipes correctly minimizes the risk of failure, ensuring long-term functionality.
