True enough if you are relying on blowing out your lines as your primary winterizing strategy. If you plan to use antifreeze in your lines almost any air is sufficient to blow enough water out to avoid diluting the pink stuff. In fact, I don’t blow any air in mine at all. Just open the drain lines for a short time then close them up and pump the antifreeze in. Takes about 20 minutes and two gallons. Works for me every time.
