My pressure regulator valve (PRV) is bad and I need to replace it. After removing the insulation around it, it looks like the union fittings aren't actually screwed into the PRV. It doesn't leak or anything, but I'm just really not sure how this is held in.
I've tried to remove this via the nuts on each side, but they're on very tight. I'm beginning to think that these are glued in and my only way forward would be to cut the PVC and reinstall with some other union fittings that connect the PVC to brass.
Does this sound like the proper way forward or does anyone else have any advice for me?
Thanks!

That regulator is both internally and externally threaded so it can be connected to multiple sizes of pipes.
I think the best way forward is to cut the CPVC after the regulator, and install the union at the cut.
