Installing, testing and servicing these devices must be done by an individual who holds a current Backflow License. Once installed, you must have it tested annually to ensure that it continues to work correctly. Just like a car, these devices have parts that wear out and need replaced. We currently have on staff several Technicians that hold the proper Licensure to Test and Certify Backflows. We can install, replace, test and service all sizes and types of Backflows.
