I hook up downstream of backflow when I winterize. If i have to, I use the last testcock to connect to, and I do not use all the cfm available. I have messed up at least three back flows by "lettin her rip" through there. My backflows ALL have unions so I remove and store in my shop......Those booklets that come with the stuff you buy is good for throwing in the trash......again.....field experiance....
