An attachment for your waterline a or hose end that will blow out your sprinklers.
You will need a compressor with an air inflation end that forces air into the valve stem and through the sprinkler lines.
Screw the attachment on to the water line or hose end. The water needs to be shut off but the water valve itself has to remain open.
