Outside tap loss of pressure

[Andypm]

I’ve lost the pressure from the outside tap. It was working fine. I have checked the washer on the outside tap and the inside stop valve seen in the picture. Not sure what the thing is to the right of the stopcock? I’ve also taken the inners out of the outside tap and turned on the water again it is low. The rest of the taps inside are all working ok pressure wise.

The thing is a double check valve and it sounds as though it is faulty.
It has a couple of one way valves that operate against springs, most likely one or both of these has jammed in the shut position.
You can try removing it and poking with a small screwdriver to see if it will free off and realign - or just buy a replacement (quite cheap)

Would this be 15mm?
