I sent this once already, but it never made it, so here it is again... I'm sure there's a diagram somewhere on the web, but the gist of it is:
1) drain it at the tank bottom, which I'm sure you've done (as suggested already). I leave mine cracked just enough for it to drip a drop every once in a while, just in case I forget to do it for a while. 2) run a horizontal line as far as possible from the compressor to allow moisture to condense, giving it a slight downhill tilt so the water will run to the inline "water separator" that you can get for $20 or so from Harbor Freight 3) drain it regularly 4) if you're going to paint with it, buy one of those little "one shot" desiccated plastic air filters that screw in between your paint gun and the air nipple as a last ditch filter to catch what little moisture makes it past the water separator (about $5, and worth it). My air system consists of a 12' long piece of 1" diameter PVC pipe fastened to the wall with an air filter/separator on the end, with a two way elbow and a quick disconnect on the end of that, with more pipe running vertically from there to the ceiling and to other locations in the shop. Copper would be even better, since cooling the air is the goal. At the paint booth at work we have a compressor sitting up on a wooden stand (to elevate it) and has a coiled copper cooling pipe running out and down to the quick disconnect (it looks like a moonshine still). There's a little fan blowing on it to cool it off, and a water trap/separator/filter to catch the water. Obviously set up by engineers, but you get the point...
