I live in NY and need to replace a failing fridge that is inside a cabinet. It has an ice maker that goes from under kitchen sink under floor the 10 feet or less to back of fridge. The line is copper and has a cutoff valve under sink but none behind the fridge. It’s never leaked in the nearly 20 years it’s been installed. I’m being told that code demands that the line be fastened to wall with cutoff behind new fridge or else the new refrigerator will not be hooked up. Is this true or an overly strict interpretation? What do I risk if I hook up old way.
