Moisture is no longer a problem after I set up long lines of black pipe and have "vertical take offs" for tools, as shown in the TP Tools Air Line Installation instructions and diagram.

I also found that a larger tip with this pressure blaster is required. So I changed the entire set up. With a quality arrangement from I copied from a more expensive blaster. Works well now. But I went through the same frustration.
