I've recently moved in to an apartment which has a Potterton Suprima 50 Central Heating system.
Now the last few weeks the system has started performing poorly, with several lock-outs (red led flashing) and the pressure gauge now shows less than 0,5 PSI.
I found a small wet patch underneath one of the valves close to the pump.
When checking the screw on top of this thing it was very loose, and water came seeping out.
As I've never lived anywhere with a CH system before, I'm not sure if this one should be open or closed, if it is a pressure valve or a bleeding valve.
If anyone could help me shed some light on this I'd be most grateful.
