What is the maximum support distance for underground plastic pipes?

The maximum support distance for underground plastic pipes is 8 feet. This specification is important because it helps ensure that the pipes are properly supported to prevent sagging, bending, or other forms of structural failure over time. Plastic pipes, such as those made from PVC or PE, are lightweight, but they still require adequate support along their length to maintain their integrity, especially under soil load conditions.

While the support distances for other materials or types of installations may vary, the 8-foot maximum for underground plastic provides a balance between material flex and structural stability. This guideline helps to ensure a long-lasting installation that adheres to best practices and safety standards in plumbing and construction.
