Good tip about the drain valve, it's a lot more convenient. I also raised mine about 4" on some oak blocks and the next thing was to install a muffler on the intake. That alone quietened my shop down by half at least. It is plug and play,remove intake filter from compressor replace with a street el screw on the muffler and screw the intake filter to the other end and your done, enjoy the reduced noise. Picked them up at the Lawrence Ks. swap meet from North Central Air out of Downs Ks. they are really nice people to deal with, I have purchased 2 of the 80 gal 18.4cfm @ 175 compressors from them, one in 96 and one in 2005, and had great service with both.( I am not affiliated with them, just want to plug some really good people with a good product)
