Hi, all.
Radiator in kid's bedroom needs bleeding ( hot at bottom, cold at top ).
Standard square-key bleed-off valve has seized and rounded. The whole valve assembly looks like it can be removed from the radiator body and replaced, using with a larger internal square key.
Can any kind soul point to a replacement bleed valve assembly which screws into the hole in a std rad? My initial groping at screwfix wasn't helpfull.
I'll also need the large square key which fits into the valve to remove it from the radiator housing ( it will be hollow to accomodate the actual bleed screw stem.. )
