none, I have no idea if that is correct but the picture offers you nothing other than what you can see. On that basis I thought one drop is not going to fill any of the cups whether they are shut off, blanked off or have holes in. People assume the tap is open because there is one drop showing. Or i could be talking just bolloxs again
The tap is not connected to anything. There is only a single drop of water in evidence-presumably a legacy from when the mains pipe was disconnected. Ergo,none of the receptacles is filled at all. I claim my chocolate egg as first prize. !
Is the right answer as either there will be water restrictions or a burst pipe stopping that much coming out
