Detailed Description for Vacuum Breaker Valves

A vacuum breaker is a safety equipment to restrict unintentional siphoning of perilous elements into a plumbing system when it experiences loss of pressure. These devices are installed at numerous points in a plumbing system and the building code may necessitate people to fix their plumbing with vacuum breakers. It is not possible to use vacuum breakers in the regions with airborne pollutants, as these pollutants could get into the system through the device.

The typical condition where a vacuum breaker will be useful is when there is loss in pressure due to a power outage or any other further problems. If the lines drain out, as may occur when taps are run by people without realizing no water is available, creating vacuum in the plumbing. This can turn into a siphon, pulling non potable liquids into the plumbing and causing contamination. The device has a small valve that unlocks when the pressure descents, permitting air to bleed into the system. This restricts the creation of a vacuum and keeps contaminants out of the water supply.

Hose bibs and faucets may have a vacuum breaker, and these equipments can also be used on other supply lines. They are part of a series of protection systems people use to keep drinking water safe. These consist of separating out drainage and sewage lines, fitting emergency shutoff valves, and so forth. The device is generally inexpensive and people can fit it rapidly, with nominal fuss, to increase the safety of a plumbing system.


A plumber can decide if a vacuum breaker is essential and where to fit the equipment. There may be sets where people should not use these equipments, or where they are basically not needed as further safety features are present and the vacuum breaker would be redundant. In the instance of a new plumbing setup, sometime will be taken by the plumber to plan out the system and regulate the placement of safety features so it will be up to code and safe to use from the very start. In retrofits, the plumber may have to systematically examine the system and its documentation to make judgments about how to proceed further.
