I am thinking of extending my moisture drain from the air tank to get closer to the drain in my shop floor. I also want to add an air outlet to the same area. Would there be a problem with using the same pipe but just putting a two foot drop below the air outlet for the moisture drain? I understand there will be moisture running down the line to the down leg, but the air will be cooler and therefore holding less water than the hot air from the upper outlet. What are you opinions? Also, why do they put the outlet from the air tank so high that it gets the hot moisture ladened air into the line?
