Why bury that manifold?

  Don't want the fittings to burst in freeze. Also while PEX can survive being frozen, I have not seen much about total number of cycles it might sustain before weakening. Edit: Also I want to be able to drink water in winter.

    I'd be curious to know how much water expands under freeze vs how much PEX is compressed at a crimp fitting. It's not the same kind of force but the relative magnitude might be interesting.

      Matt Risinger (austin-based homebuilder) did a freeze comparison between copper, pex, and sharkbite fittings some time back. It was pretty interesting. At this point, I'd probably go for PEX-A (compression band) over PEX-B (the crimp style) because of the risk of getting the crimp not completely correct. https://www.youtube.com/watch?v=OOeBJ8mDr8Q https://www.youtube.com/watch?v=OOeBJ8mDr8Q

    Also I don't believe the UV rays from the sun are good for it. I think it weakens it as it does with PVC.
