What’s Hiding in Your Pipes? The Importance of Regular Testing

The final section of our gallery reveals the “unseen” side of water safety: the debris and blockages we frequently discover during Chicago backflow testing. From mineral buildup and rusted hardware to unexpected foreign objects found inside the devices, these images highlight why annual inspections are vital. These obstructions can cause critical failures in your backflow preventer, leading to water contamination or property damage. At Chicago Backflow, our mission is to catch these issues before they become emergencies, ensuring your drinking water remains clean, safe, and protected year-round.
