Pex is supposed to be able to withstand a lot of pressure, even with frozen water inside of it (not that this is a good thing to have or try). With respect to that, you should be fine.

: Hello
: I went and purchased 100 feet of 3/4 inch pex tubing to run in a rental house for the first time. I put the tubing in the back of my truck so the tubing sat outside in freezing weather for about 12 hours. The next day I could not straighten the pex tubing out for anything. I ended up getting wrapped up in it. Wasnt sure if this is a common complaint or if the freezing cold ruined the pex. HELP?????
