Went to remove a radiator yesterday for decorating, closed the TRV and thought I'd closed the lockshield valve too but a lot of water was coming out and realised that I was actually draining the system!
I had turned the head on the lockshield valve anti-clockwise (thinking this was correct to isolate it) and then realised it should've been clockwise. Fair enough, so I tried to turn it clockwise earlier and it became much looser and then black liquid started seeping out of it. In a panic I quickly turned it back anti-clockwise to stop the black liquid, but wondered which is the correct way for isolating it now!
Can anyone step in and offer some advice?
