I want to blow out my sprinkler lines before the freezing weather gets here (I am in NJ). I have an air compressor that I can borrow but how do I attach the air compressor line to the sprinkler system to blow it out?
Here is the water line coming out of my house, into the pressure vacuum breaker, and then into the ground where the valve box is located. In previous years I have had someone come out to do it and I know they attach to that spigot in the picture but I am not sure how. What type of adapter do I need to get?

Something like this should do ya just fine. You'd just have to attach it to the faucet you have and shut off the nearest valve. Should redirect the air down your sprinkler system and blow the water out of the sprinklers. You'll probably need to have a pretty hefty air compressor though, it's probably going to take quite a bit of pressure to get through your system if it's extensive.
