I bought my compressor from HF way back in 1991 or 1992, so a couple years ago me and the SIL did a hydro test on the air compressor's tank to make sure it was still in good shape. a time before the hydro test we also added plumbing to drain the moisture out of the tank, it s been maintained and taken care of and runs like a brand new one.
I believe I kept the tank pressurized for about 20 or 25 minutes, the tank showed no pin holes or loss of pressure.
