I recently has a replacement pressure reduction valve fitted (see photo) after the old one started leaking. I never thought to ask the plumber about what the pressure should be and he never left any leaflet etc. The pressure is much less than it was so bath takes longer to fill etc but maybe it was too high before. I assume it's been set at around 2 bar looking at the gauge , what should it be, is it easy to change, and what is the red hand indicating?

The gauge is set @ just over 2 bar yes, could be brought up to 3 bar. If it's an adjustable PRV then there would be a screw in the top of the black plastic cap, turn it clockwise to increase the pressure, do it slowly till the needle gets to 3.
Thanks. What does the red hand show?

The red hand is where the gauge is preset (moved to) by the user - that indicates if there has been movement in the black hand. It indicates that the gauge may have been set to ~ 3bar and the current pressure is lower. (black hand is the actual gauge reading - red hand is the indicator)
