What is Backflow? Backflow is when contaminated water has reversed flow and entered clean water lines. It can occur at any cross-connection between clean and dirty water lines and is typically caused by a significant change in water pressure such as from a burst water main. The dirty water may contain hazardous materials like human waste, pesticides, or chemicals, so it poses a serious health concern. Backflow Prevention and Testing A safety device can be installed to prevent backflow from occurring. In the case of an unexpected or dramatic change in water pressure, this device will stop dirty water from entering the clean water supply. However, this device must be properly installed and tested to ensure that the clean water line remains free of contaminants. Municipal codes require annual testing of backflow prevention devices to ensure that they are functioning properly. You can be fined if testing is not completed on time, or the water supply to your property or business might be cut off. That is why we recommend scheduling testing well ahead of time.
