CERTIFIED: YOUR FIRST & ONLY CALL.

With decades of backflow experience and thousands of satisfied clients, we are the last backflow service provider you’ll need to call to get it all. So why not call us first? Proudly certified by the NYC Department of Environmental Protection and the NYS Department of Health, we have earned the respect—and the business—of New York City’s most demanding building owners and managers.

HEY, WE’RE FROM NEW YORK TOO.

Certified Backflow is led by a group of Brooklyn entrepreneurs. As New York natives, we know your life moves too fast to waste time with anything but the best service, at the best price. We also understand the critical role your backflow preventer plays in keeping your installation compliant with the NYC Plumbing Code, and in keeping your hard-earned dollars from being wasted on fines and penalties for non-compliance.

ALL WE DO IS BACKFLOW SERVICES.

Sure, we’re experts on everything from bathtubs to sprinklers. But we realized early on that the need for reliable, knowledgeable backflow service providers was the fastest-growing market across all of our coverage area. We are proud to NOT be general plumbers: our focus is exclusively on backflow testing, installation and repair. That frees us up to bring you truly superior, high quality, certified expertise you need and deserve.
