Not sure about yours but I haven't had a "bypass" valve for refrigeration or washer. The water valves for the. washer are behind or to the side of the washer and the valve for the fridge will be under a cabinet or behind a panel around the fridge. Those valves I never turn off unless there is a leak because they have to be opened to winterize and turning them off his a real PITA.
