Few drops came out because air is lighter than water. Anyone can correct me if I’m wrong.
Now I blow out my lines also. I leave the WH bypass open, open relief valve on WH, then open the cold bypass line and wait 15 minutes. After that empties, I pressurize to 30 and open hot low drain, repeat and do cokd. Then open water valves and put just a bit of anti freeze in toilet to keep valve seal fresh.
