Boiler leaking - anything I can do temporarily?

[Mjward]

Hello

Noticed a damp patch in basement below boiler and traced it back to coming out of the circled part of the relatively new boiler.

Can't get hold of gas engineer for a couple weeks so is there anything I can do in interim?

It's a female threaded brass piece, should it have had male cap fitted?

Would help if I added photo

That’s a pressure relief valve contact the installer as this should of been done / connected as if it blow / relieves it will shoot water everywhere

System pressure high ?

Thank you Shaun. Will see if I can get original installer out. Boiler pressurised just under 2 bar
