What type of testing must the backflow prevention assembly undergo?

The backflow prevention assembly must undergo forward flow testing to ensure its proper functionality. This type of testing is designed to evaluate the assembly's ability to prevent the reverse flow of water, which is crucial for maintaining the safety of the potable water supply. Forward flow testing simulates the normal operating conditions of the plumbing system, allowing for the assessment of how well the assembly can resist any backpressure or back siphonage that might occur.

In the context of backflow prevention, it is essential that the assembly be able to maintain its integrity during normal usage, as any failure could compromise drinking water quality by allowing contaminants to enter the system. Forward flow testing thus provides valuable information regarding the reliability of the backflow prevention assembly in real-world scenarios, ensuring compliance with safety regulations and standards necessary for public health.
