What should not be twisted or kinked during piping installation?

During piping installation, it is critical to avoid any twisting or kinking of the flexible connectors. These connectors are designed to accommodate movement and flexing, allowing for a degree of flexibility that prevents stress and strain on the piping system. Twisting or kinking can lead to restrictions in flow, increased wear, potential failure of the connector, or leaks that can compromise the integrity of the entire system.

Flexible connectors serve an important role in absorbing vibration and accommodating thermal expansion and contraction. Maintaining their integrity is essential to ensure that they function properly. If they are twisted or kinked, it can impair their ability to absorb movement effectively, ultimately jeopardizing the reliability and safety of the installation.

In contrast, the other options relate to different aspects of the installation process, where kinking or twisting would have less immediate impact or be inherently less problematic compared to flexible connectors.
