To prevent contamination due to back pressure, many health regulatory regimes require an air gap or mechanical backflow prevention assembly between the delivery point of mains water and local storage or use. Where submerged mains inflow is permitted, a backflow prevention assembly is required, which protects the potable water system from contamination hazards.


In many countries. approved backflow prevention assemblies are required by law and must be installed in accordance with plumbing or building codes A typical backflow assembly has test cocks and shut-off valves and must be tested when installed if relocated or repaired, and also on a periodic basis.

In the US, the Environmental Protection Agency (EPA) holds local water suppliers responsible for maintaining a certain amount of purity in potable water systems. Many states and/or local municipalities require annual testing of backflow prevention assemblies. In most cases, the law requires a double check (DC), Reduced Pressure Principle Device, or an air gap when backflow prevention is mandated.
