Where is my filling loop?

[melodylondon]

I need to pressurise my Vaillant ecoTEC plus 618 Boiler, but can't find the filling loop!
It's not under the boiler itself... (IMG_1696.jpg)

And I'm uncertain about the pipes around the water tank upstairs (see pictures attached) -- can you see anything there?
Where do you think it could be?

Cupboard under the boiler maybe?

Cupboard under the boiler: base kitchen cabinet with the washing machine in there... but the cabinet to the right of that is the one of the kitchen sink with many pipes... let me send a pic of that!

Ok. That would be good.

Here is to understand the set up:

This is the inside of the cabinet below the sink (it's a mess due to the double sink, the insinkerator and the hot water tap/tank!)

Have you tried this one?

I'd vote the the above, black knob should be on the lower one, on the underside.

Probably one of these or similar;

No black knob on the lower one on the underside :-(
Shall I use a key?

That looks like a normal iso to me mate.

Haven't tried it, but would need to be told what to do with it pls! ;-)

Flat head screwdriver in this part, turn a quarter turn. See if the pressure goes up. Once at about 1.2bar. Turn it back to where it is now. (Hopefully this is it)
