In plumbing systems, proper support for piping is crucial to maintain the integrity of the installation and prevent sagging or damage over time. For one inch cross-linked polyethylene (PEX) piping installed horizontally, the requirement specifies that hangers should be installed at intervals not greater than 32 inches.

This specification ensures that the weight of the piping and any potential stresses from thermal expansion or contraction are adequately supported. PEX is relatively flexible, but it still needs to be appropriately secured to avoid issues such as movement that can lead to leaks or failures.

In terms of installation best practices, the use of hangers at these specified intervals is designed to enhance the stability and longevity of the pipeline while also complying with local plumbing codes. Meeting these requirements is essential for ensuring a safe and reliable plumbing system.
