Sullair compressor is reading around 140 psi sump pressure while unloaded and blow down valve is releasing. Why isn't sump pressure not dropping?
____________________________________

What model of Sullair is yours a 185.. what?
What is the nominal operating pressure?
Is pressure normal when loaded?
Is the intake closing when unloading?
