Dripping unvented cylinder (Ed.)

[cav135]

Hi, can anyone help please. The boiler is 5 years old, just been services but i have noticed a drip coming from it. Anyone have any ideas. I have posted a picture that shows boiler type and location of drip.
Thanks

It’s an unvented cylinder not a boiler. The drip in question appears to be the drain off, so should be able to tighten it up

Thanks,
Where do i tighten it up from? There seems to be a small square nut underneath, is that it? Or is it at the cold water inlet which is just up and to the left?

Yep, tighten the square nut, use an adjustable spanner on it.

As you are looking at it, tighten is to move the square + spanner, from the left, to the right.

It should only need a fraction of a turn.

I think you mean, "clockwise"
The top rotates left to right but the bottom rotates right to left.

No, the square part, screws into a threaded socket, as would a bolt, screw into a nut, so left to right it is, if it's upside down, to tighten.
