Need HELP-regulator in Badger seems not working

Does it run up to pressure and stop or does it just run continuously? If it runs continuously, it would suggest there's an air leak in the system.

Check your air hose connections and that the drain valves in the bottom of the tank and the moisture trap are operating correctly and not venting air. 

Check the service page at Badger airbrush

They will do service on their brushes and compressors.  Labor is free.  They charge for parts at a deep discount,   I want to say 60% off. 

They do want $28 return postage.  

I have had Badger do yearly maintenance on my brushes and an satisfied with their service

See the compressor product page
