This is the first year I'm going to use compressed air to winterize.I would like to know how long to leave the taps open to make sure there is no water left.thank you
Ohio gets very cold. Air will not completely do the job because liquid can not defy gravity in all bends and low points in the lines. I blow mine out with air first but also use antifreeze and the water the antifreeze pushes out is quite a lot. We have our cold spells here in Tennessee too so I don't rely on air alone, you shouldn't either.
