How Backflow Preventers Work
A backflow preventer uses valves and mechanical components to block the backward flow of water. There are various types of backflow preventers designed to handle specific types of plumbing systems and pressure variations. Here are a few common types:
- Reduced Pressure Zone (RPZ): Best for high-risk systems, such as irrigation systems or industrial water applications.
- Double Check Valve (DCV): Commonly used for residential properties with lower risk factors.
