What Are the Main Types of Backflow Preventers?

Backflow prevention is a critical aspect of maintaining clean and safe water supplies in both residential and commercial settings. Without proper backflow prevention, contaminants can flow back into the water system, potentially causing serious health hazards.

If you’re looking for reliable backflow prevention in Long Beach, it’s essential to understand the different types of backflow preventers and their uses. Partnering with a trusted backflow prevention company in Long Beach can ensure your property stays compliant with regulations while protecting your water sources.

What is a Backflow Preventer?

A backflow preventer is a device installed in plumbing systems to stop the reverse flow of water. This reverse flow, also known as backflow, can occur due to pressure changes in the system, such as during a drop in water pressure.

Without a backflow preventer, harmful substances like chemicals, dirt, or bacteria could enter the clean water supply.

The Main Types of Backflow Preventers

There are several types of backflow preventers, each suited for specific applications. Here are the most common ones:

1. Air Gap

   
   

   This is the simplest form of backflow prevention. An air gap is a physical separation between the water supply outlet and the highest possible water level in a container. Often seen in sinks or dishwashers, it’s effective but only suitable for certain situations.

2. Atmospheric Vacuum Breaker (AVB)

   
   

   AVBs use a one-way valve to prevent backflow. This type is commonly used in irrigation systems. However, they must be installed higher than all downstream piping and cannot be under continuous pressure.

3. Pressure Vacuum Breaker (PVB)

   
   

   PVBs are similar to AVBs but are designed to handle pressure. They consist of a spring-loaded check valve and an air inlet valve, making them a popular choice for lawn irrigation systems.

4. Double Check Valve Assembly (DCVA)

   
   

   DCVAs consist of two check valves that work independently to prevent backflow. They’re often used for moderate-risk applications, such as small businesses or residential properties.

5. Reduced Pressure Zone (RPZ) Assembly

   
   

   RPZ assemblies are the most advanced and reliable type of backflow preventer. They use two check valves and a relief valve to protect against high-risk contamination, such as in hospitals, chemical plants, or industrial facilities.
