A vacuum breaker is a device often installed on a bibcock valve, toilet, or urinal flush valve to stop water from flowing back into the plumbing system. This is crucial in preventing contamination of the water supply by ensuring that dirty water or other substances do not get sucked back into the clean water lines. By creating a barrier that breaks the vacuum created by the flowing water, the vacuum breaker helps to maintain the integrity of the water supply system and protect the health of individuals using the water.

The vacuum breaker works by allowing air to enter the plumbing system when there is a drop in pressure, effectively breaking the vacuum and preventing backflow. This simple yet essential device is a key component in maintaining the safety and quality of our water supply. Without a vacuum breaker, there is a risk of cross-contamination between clean and dirty water, which can have serious health implications. Therefore, the installation of vacuum breakers is a standard practice in plumbing systems to ensure the protection of public health and the integrity of the water supply.
