The Village of Pinckney has adopted the Michigan Department of Public Health code R325.11401 to R325.11407 which requires that all PVB devices be tested on a routine basis.  Experience shows that there is not a mechanical device, which can be depended upon unless it is routinely tested and maintained.  Backflow prevention devices must be tested only by certified backflow prevention testers who are knowledgeable of the workings of the devices and fully realizes the hazards of cross connection with a potable water system.  At minimum, the State requires that these devices be tested every three years, and you are required to submit a copy of the test reports to the Village Offices.
