Kitchen Leak Investigation and Repair Required I have a kitchen leak that is appearing between the laminate floorboards. The leak often occurs after the dishwasher has been running, particularly towards the end of the cycle when it is draining. I am looking for someone with plumbing experience to investigate the source of the leak and carry out any necessary repairs.
