Understanding Backflow

In simple terms, backflow is the undesired reversal of water flow in a plumbing system. This means that instead of clean water flowing into your home or business, contaminated or used water can flow back into the pipes and contaminate the rest of your water supply. This usually happens due to a decrease in water pressure or an increase in pressure from a different source, such as a burst pipe or firefighting activity. Without a backflow prevention device, this contaminated water could lead to serious health hazards for you and those around you. 

How Do I Prevent a Backflow Issue With a Backflow Prevention Device?

A backflow prevention device works by allowing water to flow in only one direction, preventing any unwanted backflow of contaminated or dirty water into your clean water supply for drinking and other activities. These devices are typically installed at the connection point between the public water supply and your home’s plumbing system. They come in different types and can be tailored to the specific needs of your plumbing system. 

To ensure the effectiveness of a backflow prevention device, it is essential to have it installed by a licensed and experienced plumber. Your device should be tested annually to make sure that it is functioning properly to protect your water supply.
