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. A check valve is a basic form of backflow prevention, but often more complex devices are required as check valves are not considered as reliable when compared to devices with redundancies and reduced pressure zones.

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.
