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? Zach |

I've had mine for 6 years or so and rarely if ever drain it. The way I see it, it's got these big iron fittings on the bottom of the tank. If those ever rust through, it's time to go back to Home Depot. Besides, I think the compressor will wear out before the tank does.
When I do drain it, it's usually because I've been doing lots of sandblasting (heavy usage). |
