[Greenbuilding] [BULK] Re: PEX tubing

[Bruce Donelson]

I have no first-hand experience with it, but a friend (who made this
mistake) told me that you're supposed to pressurize it prior to pouring
the slab, thus preventing the concrete from compressing the PEX and,
presumably, also taking care of whatever expansion of the PEX that might
occur.

The tubing is pressurized as soon as it is installed to check for leaks or
damage. Also you might hear escaping air if it is cut. Keep pressure in it
through framing as well. Framers can shoot into tubing when fastening down
walls. Best to run the PEX through doorways, not under walls. But sometimes
doors move duriing framing....
