Backflow is a term used to describe a potential contamination hazard in water distribution systems. Potential causes of backflow include water main breaks and exceptionally high rates of water usage, like the amounts used by fire fighters. When the flow of the water drops there can be a reversal in the pressure and contaminated water can be sucked into the water line, which is known as backflow.
A plumber can install backflow prevention devices to prevent this dangerous water supply contamination risk. By accessing cross-connection sites and installing a backflow prevention device, your plumber can help ensure the safety of your drinking water. FEBCO is a company that manufacturers backflow prevention devices. They offer a great explanation of the dangers of backflow and how backflow happens on their website.
