I have a question about my air compressor.

Lately I have been turning it off when I am done working, then draining the water out via the drain plug. But once the water was out, I was leaving it pressurized for the next day. I figure that is less wear and tear then having to re-pressurize the tank every day that you need to do work, and would save time if you needed air for some other task (like charging a bike tire before going riding). if the tank was fully pressurized before I turn the compressor off, it could have ~100 psi of air after draining the water out of the bottom of the tank.

Is this harmfull?

I am taking the pressure out of the hose and setting my regulator for 0 PSI, so I don't think it would strain the regulator. Am I wrong here?

The entrained moisture laden air kills your air tools. We used to drain once per week in the hot humid summer ... slightly less in the winter. Also, we did a daily injection of oil to protect the tools.

Now, we have a refrigeration system on the output to remove the moisture.

I dribble oil into my expensive IR impact wrench. The rest of my air tools are Harbor Freight specials so if they break, I will toss them in the trash and replace them. Funny, none of them have broken yet... probably because they don't see the usage that they would in a professional shop.
