What is a key factor in determining the appropriate type of backflow prevention device to install?

The degree of hazard is a fundamental factor in determining the appropriate type of backflow prevention device to install because it directly evaluates the potential risk of contamination to the clean water supply. Different situations present varying levels of risk, ranging from low to high hazards. For instance, residential drinking water systems typically require devices suitable for low to moderate hazards, while industrial applications with potential toxic substances necessitate more robust protection, such as high-hazard backflow preventers.

Choosing the right device based on the degree of hazard ensures that the appropriate measures are in place to protect public health and maintain the integrity of the water supply system. This assessment takes precedence because it helps in complying with local plumbing codes and regulations, which are often influenced by the risk associated with backflow prevention.

While other factors like the type of water used, location of the installation, and cost of the device are also important considerations, they are secondary to understanding the level of hazard presented by the specific application. Addressing the hazard adequately ensures that the chosen device functions effectively in preventing backflow and safeguarding against contamination.
