Your trusted experts in backflow testing and services

My name is Allen DeLosa, and together with my son John, we founded American Backflow Services LLC. I have been a New York State Department of Health-certified backflow device tester since 2002, qualified to perform testing throughout New York State. Recently, I have also received the ASSE-5110 certification to provide backflow testing services in Pennsylvania.

If you’re a water customer with a backflow device requiring annual inspection, testing, repair, or replacement—or an engineer, water purveyor, or plumbing contractor in need of professional assistance—don’t hesitate to call or email us for prompt, reliable service.
