Commercial and residential buildings are generally required by state and municipal plumbing codes to install a backflow prevention device whenever there is a possibility that a backflow of water might get into the clean water system. As such, backflow testing must be performed annually to ensure proper operation, which is essential to protecting the clean water supply.

What is Backflow?

Backflow occurs when clean water reverses its direction, creating a reaction that brings dirty water into the clean water supply. This dirty water can be incredibly harmful, containing numerous chemicals, fertilizers, and human waste. Whenever a cross-connection exists between clean and dirty water, there is a risk of backflow, which is why backflow prevention devices are required in such systems.

The backflow prevention device can range from simple to complex, involving a series of check valves to keep water from flowing backward and contaminating the clean water supply during times of unequal water pressure. If properly installed and regularly maintained, this device can keep clean water safe and dirty water where it belongs.

Los Angeles Certified Backflow Testing

Having a properly working backflow device is not only a requirement, but also keeps water safe, preventing the unwanted flow of unwanted contaminants such as used water, industrial fluids, or other harmful substances from entering the pure or potable water system. You will typically receive a reminder from county authorities several weeks before testing is due. The backflow test must be performed by someone who holds a valid Certificate of Competence issued by the Los Angeles Health Officer.
