Anthony, compressor 101. The only reason that an airbrush compressor does not have many issues with water is the storage tank. A compressor produces heat as it fills the tank, that meets the cooler air of the room around it, developing condensation. Hence, water build-up. If you want the guarantee of steady pressure by using a larger compressor regulated down for airbrush use, you can get water separators and dryers to keep the water out of the system. Another trick is to run hard line piping before you connect your hoses and place a "T" in line with a pretty good drop down and a bleed valve at the bottom. The water will normally drop down the first opening it finds and a good habit would be to crack that lower valve before every use. Also, elbow up for the final hose connection. When the system sits idle, it is very difficult for the water to even reach the hoses. So, across and up, with a "T" dropping down along the way, with an easy levered ball valve works best.
