A backflow prevention assembly is used to protect water supplies from contamination or pollution.
In water supply systems, water is normally maintained at a significant pressure to enable water to flow from the tap, shower etc.
When pressure fails or is reduced as may happen if a water main bursts, pipes freeze or there is unexpectedly high demand on the water system, the pressure in the pipe may be reduced and may allow contaminated water from the ground, from storage of from other sources to be drawn into the system.
To prevent such an occurrence, many regulatory regimes require there to be 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.
In this way the backflow prevention assembly protects the potable water system from contamination hazards which can be severe. There are over 10,000 reported cases of backflow contamination each year Some cases can be fatal.

Annual Checkups
Miami-Dade as well as many other municipalities in the Unite States require annual testing of backflow prevention assemblies.
A check valve is a common form of backflow prevention. In most cases, the law requires a double check (DC), an Reduced Pressure Principle Device (RP) device or an air gap when backflow prevention is mandated.

Cross-Connection
Cross-connection control is the effort to control interconnections between drinking water supplies and non-potable substances or sources. Cross-connection control programs have been a part of water and health agency programs for decades. A concern of many agencies has been household cross-connections. Although many haven’t considered the hazards in households to be a major area of concern, it has, for the most part, remained an unknown factor in the cross-connection control field.
The US Environmental Protection Agency (EPA) had funded an epidemiology study (the Water
Evaluation Trial, or WET Study) to determine the health effects of a home water treatment unit on the residents of approximately 400 homes in four contiguous urban/suburban communities in the US Mid West. All of the WET study participants lived in single-family homes. One of the concerns, which arose, was the possibility that the water could have been pure water when delivered to the residence, but could have become contaminated through cross-connections on the premises. This question, in turn, led to the funding of this study, wherein approximately 200 of the above mentioned homes were surveyed to determine whether the potential for cross-connections in the home existed and to assess whether cross-connections in the home could result in exposure to contaminants that would cause diarrhea or gastrointestinal illness, with the health effects being measured in the WET Study.
