Vaillant Ecotec Pro 28 Filling Loop

[Darragh John]

Hi my boiler lost pressure due to a leaking radiator. Does anyone know how I can repressurise please ? I don't have the manual from when I moved in. I have identified the loop but there is only 1 valve that I can turn. Any guidance would be appreciated it. Complete novice here !

The valve on the right hand side needs a screwdriver to operate it. Looks like a DIY repair job
