Worcester boiler issue

[Skilzzz]

Hi guys, just needed someone to give me a bit of advice really. Had a Worcester Greenstar i30 boiler fitted a few years ago...all is good with the boiler...however there is a leak from a ball joint thing underneath the boiler. Not too sure what this joint actualy does but is this an issue i can fix myself? Id say a small drip every few minutes, not a massive thing or anything...any help would be appreciated.

That's a mini expansion vessel shock arrestor. If it's leaking it'll need replacing. You can do it yourself https://www.screwfix.com/p/reflex-expansion-vessel-shock-arrestor-0-16ltr/8199V
