Water pressure and Pex help


I just finished replacing a shower. I switched out the old 1/2" galvi pipe with 1/2" Pex. Now I have no water pressure in the shower! All other water outlets are fine with no pressure change. I am on well water with a 30-50 PSI.

Should I switch out the 1/2" for 3/4" or does anyone else have any ideas?

Single or double handle valve.
Most likely if it's trash stuck in the anti scald valve or the shower heads plugged up.
Any time you change out old pipes there's going to be trash knocked loose. The shower head should have been removed and the lines flushed out.

Single handle with a gravity fed tub/shower. Each is 17" from the valve with manufacture suggestion of no more than 18".

I flushed the lines for about 5 minutes, but after putting the valve on. You think trash might be stuck in the valve or the pipe to pex fitting coming off the main line?
