Winterizing Sprinkler

[tate16t]

Hey guys,

I would like to verify the process to winterize my sprinkler system. I have done this previously with my air compressor but had my backflow preventer replaced which is very different from the previous one. Attached is a link to a pic of my backflow. Can someone assist me with the steps required to accomplish this? Thank you
