Sometimes, the backflow preventer can partially open valves because of the rust or significant damage to the device. In that case, you will get a low water pressure that might cost you a huge time. Mainly, you need the fully open valves to get the regular flow of the water. It might change the entire game, but the valves are the main culprit here.
