What must be checked when replacing rigid tubing?

When replacing rigid tubing, it is essential to ensure that the new line's layout matches the old line. This is critical because any deviations in layout could cause improper installation, which might lead to issues such as misalignment or strain on the components of the system. Proper layout guarantees that the flow paths remain consistent, ensuring optimal performance and minimizing the risk of leaks or failure in the system.

The layout encompasses factors such as the bends, angles, and connection points, which must be replicated to maintain the integrity of the fluid flow and the operational efficiency of the system. Adhering to the original layout contributes significantly to the reliability of the installation and helps prevent future maintenance issues.

While checking the other aspects such as color, length, and brand may have their importance, they do not directly impact the functional requirements of the tubing replacement as significantly as the layout does. Thus, maintaining the layout is paramount in ensuring that the system continues to operate seamlessly after the replacement.
