So I had some air system issues recently. About a week ago my air started bleeding out overnight. Found out it was the check valves, so it was leaking back through the compressors. Also on the way home from work last week the compressors never turned off 15 min drive, plugged in my tank gauge 275psi
Found out my pressure sw had been collecting water even though I bleed the tanks about once a month. The sw was mounted on a lower side of a T. Now I remounted a new 165-200psi sw up so it can't happen again, new check valves and I finally mounted my 250psi blowoff valve.
