My personal Favorite Backflow Preventers to work on. The Watts 009M2. This video illustrates the simple cleaning of the parts inside a 009M2 Backflow. I took apart the backflow because it failed its annual test for a number two check leak. This video is a brief overview of how to clean the individual parts to get the backflow passing its test.
