As many in the Great Lakes Region know, it’s been a very wet summer. Raining pretty much every other day, and therefore it’s been very humid. I drain my tank after every use, but admittedly I forget to use the drain valve sometimes. However, whenever I’d use the drain valve, I’d typically get a light mist at best. Eventually I heard sloshing in the tank. I drained the tank from full pressure this time, and still barely any water came out, though the valve froze several times upon release. I decided to tip the tank upward as I still heard sloshing, and a large orange puddle came out.
I removed the large 1-1/2" bushings from the top of my 20 gallon tank and saw this. Some of the sludge is oil. I’m not sure how concerned I should be about this, though I routinely fill the tank to 175psi. I know now I should tip the tank upward after each use, but I’m not sure if it’s already too late. Needless to say, the last thing I need is my air tank to become a second stage booster for a rocket launch, at least while I’m still using it.
