Best Backflow Prevention Devices Reviewed

Ensuring the purity of your water supply is paramount for both health and compliance reasons. Backflow prevention devices play a crucial role in maintaining the integrity of your water system by preventing the reverse flow of water from potentially contaminated sources. In this comprehensive review, we explore the top backflow prevention devices available in 2024, helping you make an informed decision for your residential or commercial needs.

What is Backflow?

Before diving into the devices, it's essential to understand what backflow is. Backflow occurs when the normal direction of water flow reverses due to changes in pressure, potentially allowing contaminants to enter your clean water supply. This can happen in two ways: backpressure or backsiphonage, both of which can be prevented with the right equipment.

Types of Backflow Prevention Devices

There are several types of backflow prevention devices, each designed for specific situations:

  1. Air Gap: The simplest and most reliable method, involving a physical space between any device that opens to a plumbing system and any place where water might collect.

  2. Double Check Valve Assembly (DCVA): Suitable for low-risk backpressure and backsiphonage situations. It consists of two check valves in series, offering redundancy.

  3. Reduced Pressure Zone (RPZ): Ideal for high-risk scenarios, an RPZ has two independent check valves, separated by a pressure differential relief valve, ensuring maximum protection.

  4. Pressure Vacuum Breaker (PVB): Designed to prevent backsiphonage only, it's installed in the supply line with a spring-loaded check valve that closes when water flow stops or reverses.

  5. Atmospheric Vacuum Breaker (AVB): Similar to PVB but simpler, designed for specific situations where backpressure is not a concern.
