This. turn the compressor off, open the tank stopcock and let all the
air and water drain out. When you think it's done, don your eye
protection, and probe the stop cock's opening. (Better, remove it,
but that's asking for not being able to reinstall it...) You may well
find there's some thing (rust flakes, scale, godzilla) blocking the
free flow of water out the system. Do the same at all your drains.
I've also seen a tank where the bottom stop cock was connected to an
anti-dip tube, so that you couldn't drain the tank. (It was an
industrial application, it's entirely possible the tank was mounted
upside down from the original application, where a dip tube would work
to blow water out of the tank.
