contaminated water and backflow testing in Belleville IL


Backflow is the term that’s used for the contamination of drinking water by used, unclean water that flows back into your system from the sewer line. This can happen for a variety of reasons and at different points throughout the home, so it’s important to stay on top of this.


There are quite a few questions to the answer of where. Backflow can happen anywhere and most often occurs in older homes that aren’t prepared for this to happen. Specifically, backflow happens at cross-connections in your water lines where pressure regulates the flow of the water. While water should only flow into your home via the water lines, a reverse in pressure can create backsiphonage that reverses the flow of water back into your drinking supply.


There’s no specific time when this happens, instead the proper conditions have to be created in order for this to happen. It won’t occur at a specific time of the day or year, and it won’t be more likely to happen based on the season. The level of pressure inside your pipes is what determines this.


We can tell that this does occur when the pressure changes in the pipes due to a water main break, a clog or something else that changes the pressure.


There’s little way to find out if you’re at risk of backflow by yourself. Unless you’re a licensed plumber with the right equipment, you’ll have to call a professional to help with backflow testing .
