Commercial Backflow Prevention for Businesses and Restaurants

Testing, Repair and Installation in Washingon, DC, Maryland (MD) & Northern Virginia

The Washington Suburban Sanitary Commission (WSSC), and many other counties and local authorities having jurisdiction over the potable water supply, and now require an annual inspection of all cross-connection and backflow prevention devices by a licensed plumbing company such as Spartan Plumbing, Heating and Air Conditioning. Property owners (businesses, restaurants, etc.) are responsible for maintaining all backflow preventers by annual testing, rebuilding or replacement and being able to demonstrate and keep record of the annual testing and maintenance of such devices. Backflow preventers are devices used to protect against contaminated or polluted water from backing up in pipes and getting into drinking water when there is a sudden drop in water pressure. While you may not be aware of them, many backflow preventers probably exist in your home, business, commercial building or restaurant .
