Backflow testing is the process of testing the backflow prevention device on an irrigation system to ensure that it is working properly and preventing contaminated water from flowing back into the drinking water supply.
Backflow testing is important to prevent contamination of the drinking water supply. If the backflow prevention device is not working properly, it can allow water to flow back into the drinking water supply, potentially contaminating it with chemicals, fertilizers, and other harmful substances.
Backflow testing should be performed annually to ensure that the backflow prevention device is working properly and complying with local and state regulations.
Backflow testing must be performed by a licensed and certified professional who has been trained in backflow prevention and is authorized to test backflow prevention devices.
If your irrigation system fails backflow testing, it means that the backflow prevention device is not working properly and may need to be repaired or replaced. Your irrigation service provider can recommend the appropriate course of action to bring your system into compliance.
