What is backflow?

Backflow is the undesirable reversal of the flow of water or other liquids in a plumbing system. It can occur when there is a sudden change in water pressure, causing contaminated water to be drawn back into the clean water supply. This can pose a serious health risk, as it can introduce harmful bacteria, chemicals, and other contaminants into the water supply.

Backflow can happen due to a variety of reasons, including a drop in water pressure in the supply line, a burst pipe, or the use of a high volume of water at one time. To prevent backflow, backflow prevention devices are often installed in plumbing systems to ensure that water only flows in one direction.

Regular maintenance and testing of backflow prevention devices are essential to ensure that they are functioning properly and effectively preventing backflow. It is also important for property owners to be aware of the potential risks of backflow and take necessary precautions to protect their water supply.
