Supporting Uponor PEX pipe

Suspended runs of Uponor PEX pipe can be supported by the same conventional means as metallic pipe, using copper tube size

(CTS) hangers and supports. However, support spacing will vary depending on local code requirements.

Note: Uponor recommends using hangers and supports designed for use with plastic piping.
