Backflow Valves
Backflow prevention valves prevent water, sewage or contaminated substances from flowing back into the pipes and into clean water supplies. Such contamination usually occurs at cross connections in the water lines. The backflow of sewage, gray water or other contaminated substances into fresh water supply pipes may cause a serious health risk. Backflow prevention valves can be found in both residential and commercial properties. Almost all businesses and commercial properties are required to have plumbing backflow meters installed, and then tested every year. Backflow inspections are made to ensure that city water supplies don’t become contaminated. At All-n-One Plumbing and Drains, we can install, repair, and certify your backflow device.
