My backflow tester failed one of my devices. He said I needed to replace the backflow device. This would have been very costly and he did nothing to troubleshoot it. I called another place and they were a no-show. I contacted Van @ Titan a few times and he took the time to explain some things to me. I asked him to stop by and he did so promptly. He found a piece of plastic of some sort in my backflow and removed it while cleaning up the backflow. Then it passed and he got the forms online himself and sent them in for me. Great service and I highly recommend him over the guys that just test for cheap and end up costing you more because they don't do anything to troubleshoot the backflow.
