We are having major sewer backup problems here at 371 Berkeley Circle. The plumber has been out 2 times in the last week and 3 times in the last month. The lines have been snaked out 3 times and the problem still persists. There are no trees on the property so root damage is highly unlikely. We can only assume that the major sewer line out in the street is blocked.... please assist.
