Hi

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?

I honestly would drain it after every use... 20 Gal is pretty small
and it just does not take any time at all to fill the tank...

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?

If you want to go to the trouble of doing this just drain the tank and
walk away... again just to save the time...

I have an 80 gallon tank that I use almost every day....its close to
30 years old now and I drain the thing every single day.... I do this
to stop the tank from rusting inside the tank...and I leave the drain
open until the next use... to be truthful I really do not know if it
is required BUT I do know the tank is still solid..

Just my opinion... Just do not neglect oiling your air tools
before you store them...
