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.
