</font><font color="blue" class="small">( compressore which has the drain petcocks on the bottom of the twin tanks )</font>
It seems to me that very few air-compressors are designed with a "good" drain system. My 30 gallon vertical tank came with the petcock right in the middle of the bottom of the tank, of course, which put it so close to the floor you could barely get your hand under there and the compressor had to be tilted back temporarily to even put a pie pan under it. So I removed the petcock, put in an elbow, a 6" nipple out the side and put the petcock into the end of that. Of course that puts the drain right on the floor, so I had to put blocks of wood under mine, too. /forums/images/graemlins/frown.gif
