What are Backflow Preventers?
A backflow prevention device is used to protect city water supplies from outside contamination or pollution. These devices allow water to flow in only one direction, protecting the water supply from contamination that an end user may cause. In an unprotected system water flows both in and out of a building without constraint. If there is a pressure drop, contaminated water will be pulled backwards into the water system if not protected. Backflow prevention devices can be tested by a NYS licensed backflow tester, who examines various components such as double-check valves and reduced pressure zone devices to ensure proper function.
