Hello, I observed that there is dampness on the outside wall, could this be a leak from the water pipe running through the wall? Also, not sure what that big nut type thing is, appreciate your help here.
Yes, two storey house, no rain recently, kitchen behind the damp spot, I just realized there is a flume indication of a potential leak, could it be a copper pipe that's leaking?
The leak is constantly happening, I could see water droplets at the bottom of the wall and the dampness is not going away, will follow up with contractors, thank you
