Certified Backflow Testing & Inspection Services

Annual Backflow Prevention Testing & Certification

Municipal water purveyors and local health codes require commercial properties, multi-family residential buildings, and industrial facilities in San Francisco and the Bay Area to perform annual testing on all backflow prevention assemblies. Backflow devices protect the public potable water supply from contamination caused by backpressure or backsiphonage.
