What Is Backflow and Why Is Backflow Prevention Important?

Backflow is the undesired reverse flow of water into the public water supply. Backflow can occur for a variety of reasons, including:

  • Cross-Connections: A cross-connection is any physical connection between a potable water line and a non-potable water line. Non-potable water lines can carry a variety of contaminants, including sewage, wastewater, and chemicals. If a cross-connection exists, contaminated water can flow back into the potable water supply during a backflow event.
  • Backpressure: Backpressure occurs when the pressure in a non-potable water line exceeds the pressure in the potable water line. This can happen due to a variety of factors, such as a blocked or clogged pipe. If backpressure occurs, contaminated water can flow back into the potable water supply.
  • Backsiphonage: Backsiphonage occurs when a vacuum is created in the potable water line. This can happen due to a sudden drop in water pressure, such as a broken water main or a burst pipe. If back siphonage occurs, air can be drawn into the potable water line, which can cause contaminated water to be sucked back into the system.


Backflow prevention is important because it helps to protect the public water supply and prevent the contamination of drinking water. Backflow contamination can lead to a variety of serious health problems, including gastrointestinal illness, respiratory problems, and skin infections.

Types of Backflow Prevention Devices

There are a variety of different types of backflow prevention devices available. The type of device that is required for your property will depend on the specific backflow risks that are present.

Some of the most common types of backflow prevention devices include:

  • Air Gaps: An air gap is the simplest and most effective type of backflow prevention device. An air gap is a vertical separation between the end of a water supply pipe and the highest point of the water in the receiving vessel. The air gap must be at least 1 inch in size.
  • Reduced Pressure Zone (RPZ) Valves: RPZ valves are complex devices that protect against both back pressure and back siphonage. RPZ valves are required for high-risk applications, such as irrigation systems and fire sprinkler systems.
  • Double Check Valves: Double check valves are two check valves that are installed in series. Double-check valves are typically used for medium-risk applications, such as hose bib faucets and washing machine connections.
