General Information Backflow is defined as the reverse flow of a liquid into the potable water supply. The installation of a backflow preventer protects the water supply from contamination from this very serious condition. This product guide includes information on Watts complete line of backflow prevention devices. Should you require additional information, contact your local Watts Representative listed on the back of this guide. Code Requirements ll major plumbing code bodies address protection against backflow. ll potential or existing cross connections must be protected from backflow by the installation of a proper backflow prevention device. Consult your national and local plumbing code authorities for more specific information on your code requirements. 757 OSY Backflow Definitions Backpressure: pressure, higher than the supply pressure, caused by a pump, elevated tank, boiler, or any other means that may cause backflow Backsiphonage: backflow caused by negative or reduce pressure in the supply piping Cross-Connection: a connection or a potential connection between any part of the potable water system and other environment containing substances in a manner that under any circumstances would allow such a substance to enter the potable water system. Other substances may be gases, liquids, or solids, such as chemicals, waste products, steam, water from other sources (potable or non-potable) or any other matter that may change the color or add odor to the water. Bypass arrangements, jumper connections, removable sections, swivel or changeover assemblies, or any other temporary or permanent connecting arrangement through which backflow may occur are considered to be cross connections. ealth azard: a cross-connection or potential cross-connection involving any substance that could, if introduced into the potable water supply, cause death, illness, or spread disease, or have a high probability of causing such effects Non-ealth azard: a cross-connection or potential cross-connection involving any substance that generally would not be a health hazard but constitutes a nuisance or would be aesthetically objectionable, if introduced into the potable water supply Backflow pplications TYPE & PURPOSE DESCRIPTION INSTLLED T EXMPLES OF INSTLLTION REDUCED PRESSURE ZONE SSEMBLIES For health hazard crossconnections and continuous pressure applications.

Wiper Seal Bottom Plug Spring ssy. ow it Operates The unique relief valve construction incorporates two channels: one for air, one for water. When the relief vale opens, as in the accompanying air-in/water-out diagram, the right-hand channel admits air to the top of the reduced pressure zone, relieving the zone vacuum. The channel on the left then drains the zone to atmosphere. Therefore, if both check valves foul, and simultaneous negative supply and positive back pressure develops, the relief valve uses the air-in/water-out principle to stop potential backflow.
