Strange noise through my flat
Hello everyone
I have a 1st floor, 1 bedroom flat in a small block.Few days ago we noticed strange sound through the flat and the bedroom was the noisiest. I thought that it was downstairs neighbours doing their washing but , we could hear it in the bedroom more than kitchen. The noise sounds exactly like washing mashine on high spin with rhytmical banging as if you were washing your trainers , the noise usually starts around 9pm and goes untin next noon.I have shut off the water and electricity but the noise didn't stop. I have read about sump pumps but Our block doesn't have any basement , is there any chance the block would have somewhere some pump that could be causing this noise? The noise is cause of great anxiety to both of us so any info or advice would be greatly appreciated.thank you
