The process involves hooking a large air compressor into our irrigation lines through the use of a quick coupler. We then turn each irrigation head on through the satellite controllers to blow any water in the lines out to prevent them from freezing. It takes us all day to completely blow the water out of the system. Now we don't have to worry about any irrigation leaks until we charge the system back up in early March.
I also snapped this picture this morning of our putting green and first hole. The first snow fall of the year came on Wednesday night and early Thursday morning. It looks like there won't be any golf at least for today!
Looks like you blew out your irrigatin system just in time!
