Can you split PEX pipe?
Pex should have enough elasticity to not be damaged if it is frozen, but a fitting will not. If the pipe was scored when threading it in place, that will create a weak point, though, or if it is held tight in a pinch point – movement over time through thermal expansion/contraction could wear a hole, but not a split.
How often do you need to support PEX?
every 32 inches
Make sure that PEX is adequately supported Horizontal runs of PEX must be supported every 32 inches if hanging, or every 72 inches if installed above beams. For vertical runs, PEX must be supported at least once per floor, and also keep in mind that joints add weight and require dedicated support as well.
Will PEX pipe burst if frozen?

What can I do to prevent PEX tubing from leaking?
Over time, these small movements can wear away the outer surface of the pipe and create leaks. To stop this problem before it occurs, use plastic suspension clips to cover the pipe where it passes through holes in metal or wood studs. You can also use foam pipe insulation to protect PEX tubing that runs parallel to a stud or joist. 3.
