I have been hearding pipe or plumbing noises. You know the noises you heard when you live in an apartment building, when someone in the building cuts the water on and off or flushes the toilet. There's a house in back of us owned by the same landlord but not joined to my house and they pay a separate water bill so I wouldnot be hearing their water noises would I? What could possibly be causing the noises ? Anybody got a answer for me?
