Running Pex outside of wall cavity?

[iced98lx]

Hey folks, I have hot and cold water to the garage, but it's on the most inaccessible wall (the spigots are legit in the walkway from man door into the house). I want to run some lines over to another wall where I can put a sink and hook up the pressure washer etc etc.

The garage is drywalled/insulated and heated all winter (50-55 degrees all winter) but I don't want to put the pipes in the ceiling (it has just basic fiberglass 4 inch paper face) so my thought was stuff pex into PVC and run it up the wall and across the ceiling and down to the fixtures... I know I can't leave pex exposed to UV...

What other options am I ignoring?

Can put it in a casement if you want to hide it

Copper pipe which would be ideal in this situation.

If you want to totally hide it without going into unconditioned space, and are willing to spend a lot of time on the project, build a shallow little chase framed with 2x2’s and cover with Sheetrock and paint to match.

Look at the pvc that is used for wire conduit. It's grey vs white but it's major advantage is relatively large radius bends. Also they swell one end on each section so no need for joint pieces. Paint it w/ one of the plastic paints and hang it w/ plastic hangers.

Like Firebrick said, copper is ideal for this situation. If you can't sweat copper together, CPVC would also be a good option. Shark Bites are also an option if working with copper and you can't sweat. PEX needs more support to run across a ceiling like that than copper or CPVC. Copper doesn't need protection from UV, but CPVC does if it's in an area that gets constant sunlight. If you don't have sun shining on the lines when your doors are closed, I wouldn't worry about UV exposure to them at all.

You could use 1" lumber for the side walls of your chase.

That might work but the corner beads would probably have to be trimmed. I’m not sure.
