ENDING THE CONFUSION
We often receive calls from companies that want us to calibrate their backflow preventors, onsite. Please note, we do not offer that service. Our customer base is for master plumbers. We certify their backflow test kit, which they then in turn, use this kit to certify your backflow preventor
