What is a vacuum breaker, and how does it work?
A vacuum breaker is a device installed in plumbing systems to prevent backflow and protect potable water supplies from contamination. It functions by allowing air to enter the system when a negative pressure or vacuum occurs, thus breaking the vacuum and preventing siphoning of contaminated water back into the clean supply. This simple yet effective mechanism is essential in applications like irrigation systems, faucets, and boiler systems.
The design of a vacuum breaker typically includes a valve and a vent that opens when negative pressure is detected. When the normal flow of water is resumed, the valve closes automatically, ensuring that the clean water supply remains uncontaminated. By maintaining proper air pressure in the system, vacuum breakers play a crucial role in safeguarding public health.
What are common causes of vacuum breaker leaks?
Vacuum breaker leaks can occur due to various factors, with the most common being wear and tear over time.
