What is backflow testing?

Backflow testing is the process of verifying that a backflow prevention device is functioning correctly and effectively preventing the reverse flow of contaminated water into a potable water supply. Backflow prevention devices are typically installed in commercial and residential plumbing systems to protect against the potential contamination of drinking water.

There are two main types of backflow prevention devices: backflow prevention assemblies (BPAs) and backflow prevention devices (BPDs). BPAs are typically used in commercial and industrial settings, while BPDs are more commonly found in residential plumbing systems.

Backflow testing should be performed regularly to ensure that the backflow prevention device is working properly and in compliance with local regulations. Testing is usually conducted by a certified backflow prevention technician using specialized equipment to measure the effectiveness of the device in preventing backflow.

Failure to properly maintain and test backflow prevention devices can result in contamination of the potable water supply, potential health risks, and costly fines or penalties. It is important to schedule regular backflow testing by a qualified technician to ensure the safety and integrity of the water supply.
