There are two types of devices that are used to protect water systems from contamination: vacuum breakers and backflow preventers. Both devices serve the same purpose, but they work in different ways. Vacuum breakers are installed on the supply side of the water system, where they allow water to flow out but not back in.
Backflow preventers are installed on the demand side of the water system, where they allow water to flow in but not back out.
When it comes to protecting your home or business from water contamination, you have two main options: a vacuum breaker or a backflow preventer. Both devices serve the same purpose, but they work in different ways. Here’s a look at the key differences between these two types of water protection devices.
A vacuum breaker is a simple device that prevents contaminated water from flowing back into your home or business. It does this by creating a physical barrier that only allows water to flow in one direction. Vacuum breakers are typically installed on outdoor faucets and hose bibs.
A backflow preventer is a more complex device that uses Pressure Vacuum Breakers (PVBs) to keep contaminated water from flowing back into your home or business. PVBs are installed inside your plumbing system and work by allowing water to flow in only one direction. Backflow preventers are typically required for homes and businesses that use chemicals or other pollutants that could contaminate their water supply.

Is Vacuum Breaker Same As Backflow Preventer?
A backflow preventer is a device that helps to keep water from flowing backwards into your home. A vacuum breaker is a device that helps to keep water from being sucked back into your home. Both devices are important in keeping your home safe from water damage.
When Should You Use a Vacuum Breaker?
A vacuum breaker is a device that is installed in a plumbing system to prevent backflow. Backflow is the undesirable reversal of flow of water or other liquids in a piping system. This can happen when there is a decrease in pressure in the system, such as when a fire hydrant is used or when power is lost to the pumps that move water through the pipes.
Vacuum breakers are designed to open and release any built up pressure so that backflow does not occur.There are two types of vacuum breakers: atmospheric and pressure type. Atmospheric vacuum breakers are installed on the highest point of a piping system, and they rely on gravity to function.
Pressure type vacuum breakers are installed inline and use a spring-loaded check valve to open and close.Atmospheric vacuum breakers are typically used for irrigation systems, while pressure type vacuum breakers are used for pressurized systems, such as those found in commercial buildings. Both types of devices should be tested regularly to ensure they are working properly.
What is the Difference between a Vacuum Breaker And a Check Valve?
A check valve is a mechanical device that allows fluid to flow in only one direction. Check valves are often used in pumps and other hydraulic equipment to prevent fluid from flowing back into the system.A vacuum breaker is a device that prevents the formation of a vacuum.
Vacuum breakers are often used in piping systems to prevent the collapse of the system.
How Does a Vacuum Breaker Backflow Preventer Work?
A vacuum breaker backflow preventer is a device that helps to keep water from flowing backwards into a home or business. This can happen when there is a power outage or when the water pressure in the system drops. The device consists of a check valve and an air gap.
The check valve prevents water from flowing backwards through the system and the air gap provides a space for air to enter, which prevents a vacuum from forming and keeps water from being drawn back into the system.

Vacuum Breaker Valve
A vacuum breaker valve is a device that is installed in a piping system to prevent the formation of a vacuum. The valve allows air to enter the system when the pressure drops below atmospheric pressure, which prevents the collapse of the piping system. Vacuum breaker valves are used in many industries, such as water treatment, chemical processing, and food and beverage manufacturing.
Atmospheric Vacuum Breaker
In an effort to improve the quality of our air and water, many municipalities are now using atmospheric vacuum breakers (AVBs) on their storm drains. AVBs are designed to prevent backflow of contaminated water into the municipal water supply. Backflow can occur when there is a sudden change in pressure in the system, such as during a power outage or when a pump fails.
When this happens, contaminated water can be forced back into the clean water supply.AVBs are installed at the highest point in the system, typically at the end of a pipeline where it meets the atmosphere. They work by allowing air to enter the system when there is a drop in pressure, which prevents backflow from occurring.
When installed properly, AVBs can be highly effective at preventing contamination of our drinking water supplies.
Atmospheric Vacuum Breaker Vs Pressure Vacuum Breaker
When it comes to atmospheric vacuum breakers (AVBs) and pressure vacuum breakers (PVBs), there are a few key differences that you should know about. For starters, an AVB is designed to protect against back siphonage, while a PVB is designed to protect against both back siphonage and backflow. Additionally, an AVB must be installed at least 12″ above the highest downstream water level, while a PVB can be installed at any height.
Finally, an AVB will automatically close when not in use, while a PVB must be manually opened and closed.So, which one is right for your needs? If you’re simply looking to protect against back siphonage, then an AVB will suffice.
However, if you’re looking for protection against both back siphonage and backflow, then a PVB is your best bet. Just keep in mind that you’ll need to manually open and close the PVB when needed.
Conclusion
There are two types of devices that are used to keep water from flowing back into your home’s potable water supply: vacuum breakers and backflow preventers. Both devices serve the same purpose, but they work in different ways.A vacuum breaker is a simple device that is installed at the highest point in your plumbing system.
When the water pressure in your system drops, the vacuum breaker prevents water from flowing back into your pipes.A backflow preventer is a more complex device that is installed in your plumbing system near the main water shut-off valve. Backflow preventers use a series of check valves to keep water from flowing backwards into your potable water supply.
