Backflow testing is an essential part of maintaining a safe and clean water supply. Backflow occurs when the flow of water reverses, causing contaminated water to flow back into the clean water supply. This can happen when there is a drop in water pressure, such as during a water main break or when a fire hydrant is opened. Backflow can also occur when there is a cross-connection between a clean water supply and a source of contamination, such as a chemical tank or sewage system.
To prevent backflow and protect the water supply, backflow prevention devices are installed in buildings and homes. These devices are designed to prevent contaminated water from flowing back into the clean water supply. However, these devices can become faulty over time, which is why regular backflow testing is necessary. Backflow testing involves checking the backflow prevention device to ensure that it is working properly and is still protecting the water supply.

Understanding Backflow
What is Backflow?
Backflow is the reverse flow of water in a plumbing system. It occurs when the pressure in the system drops, and the water flows back into the main water supply. This can happen due to a variety of reasons, such as a burst pipe, a water main break, or a sudden drop in water pressure. Backflow can introduce contaminants into the water supply, making it unsafe for consumption.
Backflow can occur in any plumbing system that is connected to a public water supply. This includes residential, commercial, and industrial systems. To prevent backflow, backflow prevention devices are installed in the plumbing system. These devices ensure that water only flows in one direction, preventing contamination of the water supply.
Types of Backflow: Backpressure and Back Siphonage
There are two types of backflow: backpressure and back siphonage. Backpressure occurs when the pressure in a plumbing system exceeds the pressure in the main water supply. This can happen due to a variety of reasons, such as a pump or a pressurized container connected to the plumbing system. Backpressure can cause contaminants to be forced back into the main water supply.
Back siphonage occurs when the pressure in the main water supply drops below the pressure in the plumbing system. This can happen due to a variety of reasons, such as a water main break or a sudden increase in demand for water. Back siphonage can cause contaminants to be pulled back into the main water supply.
To prevent backflow, backflow prevention devices are installed in the plumbing system. These devices ensure that water only flows in one direction, preventing contamination of the water supply. It is important to have your backflow prevention device tested regularly to ensure that it is functioning properly. This can be done by a licensed plumber or a certified backflow prevention tester.
Backflow Prevention Devices
Backflow prevention devices are essential for protecting public water systems from contamination. These devices work by preventing the backflow of water from a customer’s system into the public water supply. There are several types of backflow prevention devices, including check valves, relief valves, pressure vacuum breakers, reduced pressure zone assembly (RPZA), and air gaps. Each type of device is designed to prevent backflow in different ways.
Check Valves
Check valves are one of the simplest types of backflow prevention devices. They work by allowing water to flow in only one direction. When water tries to flow in the opposite direction, the valve closes, preventing backflow. Check valves are commonly used in irrigation systems and fire sprinkler systems.
Relief Valves
Relief valves are designed to prevent backflow caused by changes in pressure. They work by opening when the pressure in the system exceeds a certain level, allowing water to flow out of the system and preventing backflow. Relief valves are commonly used in boilers and other systems where pressure changes can occur.
Pressure Vacuum Breakers
Pressure vacuum breakers (PVBs) are designed to prevent backflow caused by backpressure and back-siphonage. They work by creating a barrier of air between the water supply and the customer’s system. If backflow occurs, the air barrier is disrupted, causing the valve to close and preventing contamination of the public water supply. PVBs are commonly used in irrigation systems and outdoor faucets.
Reduced Pressure Zone Assembly (RPZA)
Reduced pressure zone assemblies (RPZAs) are designed to provide the highest level of protection against backflow. They work by creating two check valves and a relief valve in a series. If one of the check valves fails, the second check valve and relief valve prevent backflow. RPZAs are commonly used in industrial and commercial applications.
Air Gaps
Air gaps are the simplest and most reliable type of backflow prevention device. They work by creating a physical separation between the water supply and the customer’s system. Air gaps are commonly used in dishwashers and other appliances that require a water supply.
In conclusion, understanding the different types of backflow prevention devices is crucial for protecting public water systems from contamination. Each type of device has its own unique advantages and disadvantages, and choosing the right device for a particular application requires careful consideration of the system’s needs and requirements.
Importance of Backflow Testing
Backflow testing is a crucial process that ensures the safety and quality of potable water supply. Backflow happens when contaminated water flows back into the water supply system, potentially causing serious health and safety concerns.
