A backflow prevention device allows water to flow in one direction, protecting potable water supplies from contamination or pollution due to backflow. Serious contamination can result in leading to illness and even fatalities. For this reason, it’s important to test it and fix problems immediately.
I test residential and commercial backflow valves, and also valves online to fire system. After certification, I provide the paperwork on-site and file the test report with your appropriate agencies. I’ll contact you a month before your next annual certification. Service is available in Chicago and all suburbs.
