Hi All, looking to DIY my sprinkler winterization this year. I can't determine which nozzle to hook up my compressor to.https://ift.tt/2zwiD6t is in my basement. The water source is coming up from the bottom, so I've closed that off. The bottom nozzle is below that, so it's just water. The next two are part of the backflow preventer, and the top one is just below the valve to the system. Would I hook up the compressor to that top nozzle, then open one zone at a time? Thanks! via /r/DIY https://ift.tt/2QtqtoU
