I just wanted to ask the technical folks here how do you guys drain your air compressors?
I have a Sears 6 hp 30 gal 175 psi big red one, and there are stickers all over it to drain after each use to get rid of the water that will condense in there. The manual is vague on my questions...
Do you open the drain at the bottom and let everything drain out after each use? Or just let the water out, and then close the petcock, leaving the tank with some air in it?
The last time I ran it the dew point was near 70F and quite a bit of water spewed out when I went to drain it at the end of my work session. Lately I shut off the power and open the drain when I'm done with it, then when I'm ready to use it again I let it run a bit to let any residual water out before I close the petcock.
Sorry if this is in the wrong forum but I didn't want to ask this in the tech help forum.
Thanks, Bob
