What is Vacuum Breaker?

A vacuum breaker is a device that prevents backflow of water into the potable water supply. It is commonly used in plumbing systems to protect against contamination from non-potable sources.

How does a Vacuum Breaker work?

When water pressure drops in the plumbing system, a vacuum can form, which may siphon water back into the supply. The vacuum breaker opens to allow air into the system, breaking the vacuum and preventing backflow.

Types of Vacuum Breakers

There are two main types of vacuum breakers: atmospheric vacuum breakers and pressure vacuum breakers. Atmospheric vacuum breakers are typically used in low hazard applications, while pressure vacuum breakers are used in high hazard applications.

Benefits of Using a Vacuum Breaker

Using a vacuum breaker helps to ensure the safety and quality of the potable water supply by preventing contamination. It also helps to comply with plumbing codes and regulations.

Installation of Vacuum Breakers

Vacuum breakers should be installed at the highest point in the plumbing system to be effective. They should also be regularly inspected and maintained to ensure proper functioning.

Common Issues with Vacuum Breakers

Common issues with vacuum breakers include leaks, clogs, and failure to open. Regular maintenance and inspection can help to prevent these issues and ensure the proper functioning of the device.

Conclusion

In conclusion, a vacuum breaker is an essential device in plumbing systems to prevent backflow and protect the potable water supply. By understanding how vacuum breakers work and the benefits of using them, homeowners can ensure the safety and quality of their water.
