I just bought an air compressor, 20 gal tank. I will probably use this about once or twice a month and for max 10 to 15 mins most times - just for quick jobs in the garage.
Q1. Do I have to drain the air from the tank after each use?
Q2. If the air doesn't have to be drained, should I bleed the water from the drain cock after each use? every week? every month? Do I have to lower the pressure (150lb max) in the tank before bleeding off the water? If so, to what level?
