Outdoor hot and cold faucets, idea was to attach 1/2 pex to faucets and run through 1 1/2 pvc piping about 12" under ground for an Outdoor sbower, before pavers are installed. Both pex lines fit in the 1 1/2 pvc, then arc upwards on each end until vertical. Due to supply chain issues, I could only find 1 1/2 pvc. Will it be too tight a fit to run both 1/2 pex together over the 30ft straight run? Or am I better separating hot and cold into 2 pvc runs or do I need a larger pvc pipe ( 2 inch or larger)?

If you tested that both lines fit into the PVC, then both lines fit in the PVC. If the two bends were made with a heat so that they are super long sweeps, then they won't give you much problem either. If you are using store-bought bends, then you don't have a chance. However, if the ends are short and the pex is installed into the straight pipe first, then the bend can be installed over the pex and glued onto the pipe last for a much easier job. I have created a few impossible pulls using what I call the 'install the pipe over the wire' technique.
Wire pulling lubricant always helps a lot and is often the difference between possible and impossible.
I find it interesting the you are putting the pex into another pipe.
