Orion Township’s Cross Connection Control Program was approved by the State of Michigan in 1991. Since then, commercial properties and sub division irrigation accounts have had routine inspections of backflow devices and annual reports are submitted to the township on testable devices.
However, a new MDEQ mandate requires all testable backflow devices on residential homes be tested every 3 years. A typical testable backflow device you will find on a residential property will be a Pressure Vacuum Breaker (PVB) installed on a lawn irrigation line. This device will be on the outside of the home and designed to prevent pesticides or herbicides from entering the water system. Beginning in May 2019, Orion Township shall require all testable backflow devices in residential properties be tested every 3 years.
Only Licensed Plumbing Contractors can test, repair, and install Backflow Assemblies pursuant to State of Michigan Law – Public Act 733 (State Plumbing Act) of 2002. Further, effective January 1, 2019, the plumbing contractors must be ASSE 5110 certified through the State of Michigan.
