PEX is continuing to receive broader acceptance in the industry with more engineers specifying the pipe for domestic water and hydronic distribution applications and more contractors preferring to install it.
While PEX has long been accepted in the code and listed to various plumbing and hydronic standards and applications, some engineers are still hesitant to specify it, simply because metallic systems have been the specified norm for so long as the default basis of design.
To challenge this misconception about PEX expansion characteristics, a team at Fleming College in Peterborough, Ont., used the state-of-the-art plumbing design and training lab called “Kube” in their Kawartha Trades and Technology Centre to set up a real-world comparison between PEX and copper in riser applications.
