Kevin. Interesting that all those sites say pipe should flow down to take the condensation away from the compressor and yet they show the pipe going up to the ceiling. I have a stand up compressor and ran the pipe to the wall and then made a radiator effect by running galvanized pipe horizontally back and forth down to the floor. That is where I put my clean out filter. I then ran the UV/PVC back to the ceiling and over to the three drops. Poor mans dryer. Interesting sites.
