Whistle sound from behind wall

[biffta]

Alright chaps!

Could anyone tell me what is causing the noise in the video below?

It's coming from my neighbour's side of the wall so I cannot easily investigate. But it seems to be relating to the pipes near here kitchen sink.

It occurs randomly over the course of day & night.

Thanks in advance!

Over zealous kettle??? But seriously, it could be her kitchen tap, it could be the incoming mains with maybe some debris or a loose part in the stop tap. Could also be sound transmitting back down the pipework from where the ball cock fills her CWSC in the loft

Haha I wish it was as simple as a kettle! She actually let me into her flat to investigate and I couldn’t make it happen when I was there and I tried using her taps.

The stop tap is a possibility I suppose. I actually tried moving that as well but it was stuck solid. Thoughts?

I’ve had that before turned out to be an isolator hidden inside boxing and was only opened a fraction so was causing restriction causing a flow noise
