Our company was formed in 2007, at a time when no other Master Plumber was focused on RPZ devices. Backflow Prevention founder, Paul Paddock realized this little-noticed set of devices that regulate “back siphonage” was about to become a big issue in New York City. With construction and growth at record highs, and city infrastructure under constant repair, Paul understood that Backflow Prevention devices would need expert attention and ongoing service. When New York City law changed in 2008 to mandate testing, Backflow Prevention of New York was ready.
