Hi all, hope you can help.
I have one radiator that won't heat up. After watching a few YouTube vids I've already tried a few things.
I've booked the radiator though only a little air came out. I've checked the TRV pin which is ok.
I'm now looking at the Lockshield valve which I can't get to turn. All the videos I've seen show a valve that looks like the head of a flathead screwdriver. The one I have is a tube with two of the outer edges flattened off.
Is there a specific tool/key I need for this?
