Hi My name is Tom I am new here. Would anyone be able to tell me what the fitting arrowed below is please? It is leaking but I don't know what it is to order a replacement.
Thanks
Ah I thought it looked like a pressure release. Thanks for letting me know. Reason it is leaking is due to age/corrosion I think. The heating isn't even turned on and the pipes are cold.

Heat destroys the seal on those relief valves. Looks like a 3/4" valve. A better relief valve would be the type with a round head on them, often red & they can be got with different pressure limits.

and if, as I hinted, your system has a blockage in it and you turn it on, you may find your dealing with a sealed system and not a gravity fed one, which is why you need a plumber to check its all ok
I know it is a valve fitted to ov systems, - they were often used straight into oil boilers here years ago. They could have been set at any tightness & therefore pressure limit & that's partly why I hate them. I should have added that the proper valve which may be 3bar max needs a discharge to outside obviously.
