In any of these situations, if a backflow condition occurs and some type of properly operating backflow prevention device is not present, contaminated water/liquids can be siphoned back into your home's water supply and possibly into the water distribution system for the community. If these are connected to the public water supply and enough pressure is created within one of these systems, it can force contaminated water back into the water supply. There have been several cases of "blue water" reported as coming from faucets of homeowners.
We are certified by the State of West Virginia Bureau of Public Health, as well as ASSE (American Society of Sanitary Engineering) as a certified backflow device tester. We hold additional ASSE certifications in repairs, installation, consulting and cross-connection control surveys.
