{"value":"Backflow Prevention Assembly\nA backflow prevention assembly or backflow preventer is a mechanical valve arrangement, which is designed to prevent the "backflow" or reversal of flow of water, once it has passed through the valve. There are different types of backflow preventers for different uses, and different degrees of hazard.\n\nBecause the backflow preventer is a mechanical device with springs, moving parts and rubber seating surfaces, which wear over time, it must be tested upon installation and every year thereafter to ensure that the assembly is working properly."}
