I have removed the cover of my concealed shower valve. It's a hudsun Reed I think. I have removed the grub screw but nothing else seems to move. i don't know what to do next. Have photos.
OK apply or spray in WD-40 it will help make it easier to work on it. And if you are working on the leaks area first thing make sure you quickly look and identify the mains systems were you can short down the entire water system to avoid flooding. Then the next step is to look for all the isolating values very important the wd40 spray then carry on the job
