PEX PIPE?

We ran over a fallen limb which caused my rear passenger side tire to teplode. In doing so it damaged my wheel well skirt and snapped off my two fresh water PEX type drain lines located behind the tire. The two fresh water pipes run from drivers side through floor and exit through the exterior bottom. Both pipes were bent forward and the exterior floor covering was also torn a bit. I gently turned the pipes to their original vertical position. How do I fasten new valves onto these pipes? I have never worked with PEX. Do you think the coupling inside the floor will leak since I rotated them back to vertical? Thans
