Hi guys, luckily I went looking for my water supply stop valve in a
non-emergency, because when I found it, it was seized solid
(incidentally, also buried by a criminal kitchen redesign). I've tried
moderate force, vinegar (for limescale) and penetrating oil. All
without any success. Is there any point heating it/cooling it? or does
anyone have any other useful hints before I have to ring a plumber to
free it?
