A 1 inch backflow preventer prevents the reverse flow of polluted water from entering the city’s main water supply due to a situation referred to as backflow, or back-siphonage.  It consists of a bronze body, check valves, stainless steel springs, shutoffs and test cocks for easy testing and draining.

Federal law now requires the installation of backflow preventers in cities across the United States as a means of protecting the potable water supply in municipalities.

In Texas, for affordable backflow testing, service, repair and backflow preventer installation, call City Backflow Testing.
