Isolating water sources from possible cross-contamination is often required in a variety of applications. Metropolitan has mastered the protection of potable water supply via our Air-Gap Break Tank Systems. Utilizing the concept of a physical air gap, Air-Gap Break Tank Systems prevent the direct contact between potable water and non-potable water within a building or facility. Air Gap Break Tank Systems provide several safeguards to ensure that the two water types can never cross-contaminate. Rising water within a break tank spills out via overflow exits before ever coming close to a supply pipe opening, preventing cross-contamination via either backsiphonage or backpressure backflow.
Physical air-gaps are one of the simplest, most reliable means for preventing back flow, having been implemented for a variety of applications where cross-connection exists, including treatment plants, lift stations and laboratories. Air Gap Break Tanks are equipped with their own boosting pump systems to ensure that the proper movement of water is possible and is delivered to the end-user at the necessary pressure that is both comfortable and compliant to code.
