Can the PRV be fitted to 22mm plastic pipes, assuming I use suitable pipe inserts?
I'm intending to fit this under the bath just prior to a thermostatic mixer. The shower runs hot enough but bath is overwhelmed by cold supply pressure even after fitting a check valve to the hot inlet.

Yes, PRV can be fitted to 22mm plastic pipes in case you are using suitable pipe inserts. If the one installed is the compression fitting pressure reducing valve, then the attachment to the plastic pipe depends on what the guidance is from the manufacturer of the plastic pipe.
