Hi all , went to a small top up on 30i yesterday at daughters house. Turned key , opened white valve gently , then water started to drip from right of filling key. Appeared to be coming from a small black knob to right of key.
This seem a little loose so gave a gentle tighten. Any ideas what this is?
Pressure relief? Need to loosen again?
Cheers for looking
