Question about Air Tools & Compressors
The pinhole leak is most likely your problem. However pressure switch leaks are often misdiagnosed.
Drain all the air from your tank.
Follow the 1/4" copper or plastic line that connects to the pressure switch back to where it meets a fitting that screws into the tank.
Take the lines off of that fitting and take the fitting out of the tank. That is your check valve. Be sure that isn't leaking or obstructed in anyway.
If it isn't leaking or obstructed I think you need to replace your pressure switch. Without having hands on access to your unit I can't be sure.
