What is a Backflow Preventer?

backflow preventer is a vital device that helps protect your water supply from contamination. It is designed to prevent the reverse flow of water, which can occur when there is a sudden drop in water pressure or a back siphonage event. Backflow can cause harmful substances, such as chemicals or bacteria, to enter your drinking water.

How Does a Back Flow Preventer Work?

A backflow preventer uses a series of valves to create a barrier between your water supply and any potential contaminants. When water flows normally, the valves remain open, allowing water to pass through. However, if there is a sudden drop in pressure or a back siphonage event, the valves close, preventing water from flowing backward.


Why Do You Need a Back Flow Preventer?

A backflow preventer is essential for protecting the health and safety of your water supply. Without a backflow preventer, your water could become contaminated with harmful substances, posing a risk to you and your family. Additionally, many municipalities require the installation of backflow preventers to comply with local plumbing codes and regulations.

Types of Back Flow Preventers

Several types of backflow preventers are available, each designed for different applications. Some common types include:

  • Pressure Vacuum Breaker (PVB): This type of backflow preventer is commonly used for irrigation systems.
  • Double Check Valve Assembly (DCVA): DCVAs are often used in commercial and industrial settings.
  • Reduced Pressure Zone (RPZ) Assembly: RPZ assemblies are typically used for high-hazard applications, such as fire sprinkler systems.

Benefits of Installing a Back Flow Preventer

Installing a backflow preventer offers several benefits, including:

  • Protection: A backflow preventer provides additional protection for your water supply, ensuring it remains clean and safe.
  • Compliance: By installing a backflow preventer, you can ensure you meet the requirements set forth by your local plumbing codes and regulations.
  • Peace of Mind: Knowing that your water supply is protected from contamination can give you peace of mind and eliminate any concerns about the quality of your drinking water.

Backflow preventers play a crucial role in safeguarding your water supply. By preventing the reverse flow of water, these devices help protect against contamination and ensure that your water remains clean and safe. Whether you are a homeowner or a business owner, installing a backflow preventer is an intelligent investment in the health and safety of your water supply.
