Backflow Preventers and Sprinkler Systems – Basic – James D. Lake

Backflow is the process by which water from within a system that is connected to a potable water supply "flows backward” from the system into the water supply piping. Because sprinkler systems are typically connected to the municipal potable water supply there is concern on the part of the water purveyors regarding the potential for sprinkler system water to backflow into the potable system resulting in contamination. This seminar will explore the background of concerns on the part of water authorities; the subsequent impact of regulations on sprinkler system installations, and how the impact can be mitigated.
