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

I keep the air going until the water stops flowing. It doesn't take long...Maybe 15 minutes.

I use about 35lbs and first open the hot water valves one at a time and then the cold water and toilet. I have the pump running during this procedure.
I then put in antifreeze.

Maybe the antifreeze is overkill but one morning last February I let the Labrador out to whiz and it was minus 41.
