A vacuum breaker is an attachment commonly placed on abibcockvalve or toilet or urinal flush valve, that prevents water from being siphoned backward into the public water system. This prevents contamination should the public water system's pressure drop.
A vacuum breaker typically contains a plastic disc that is pressed forward by water supply pressure, and covers small vent holes. Should the supply pressure drop, the disc springs back opening the vent holes (which let in outside air), and preventing backflow of water.
This is a one way valve that saves the integrity of the fresh water system by NOT allowing contaminate water (water contaminated with perm solution, neutralizer, hair color, etc.) from mixing with the fresh water system that we drink. Consult your local plumber and building codes for need of this product. |
