Just noticed today a small leak at a valve forming a T joint
exiting the top of my combi boiler hot water to immersion heater pipe, tighten half a notch but still leaks slightly when boiler is off & water cold.
Looking at the soldered straight joint it appears to be a compression valve
screwed into the soldered joint and open at the cap compressing a spring inside. Is this some kind of non return or bleed valve I am struggling to find anything like it on the heating suppliers websites?????????? the system is probally around 15-20 years old!
