Please can anyone give me some advice?
I have discovered exactly where the water is dripping from, it is coming from where the arrow is pointing too on my bathroom rad. All other valves are dry. What is that part called that the red arrow is pointing to do you know? When I turn that part with my hands (which I think turns rad on and off) lots of water drips out. When I do not turn it, it drips every mins or two.
Is it something that a total amature can fix? If so how? Does this part even come off? I tightened the other valves but made no difference, still leaking from that same place.
please see pic.
