What is one of the benefits of using flexible piping types like CSST?

Lower cost compared to steel
Ease of installation
Greater durability
All of the above

The correct answer is: Ease of installation

Choosing flexible piping types like Corrugated Stainless Steel Tubing (CSST) provides several notable advantages, including significant ease of installation. This is primarily due to the flexibility of CSST, which allows it to bend around obstacles and be routed in a more straightforward manner compared to rigid piping such as steel. The lightweight nature of CSST also means that it is easier to handle, reducing labor time and effort during installation, which can lead to quicker project completion. While lower cost and greater durability can also be benefits associated with flexible piping types, the standout feature that truly streamlines the process is its ease of installation. Some projects might not see a reduction in costs or may require special considerations to ensure durability, making ease of installation a consistently reliable advantage in a variety of scenarios.
