Campbell Hausfeld takes a long time to reach pressure
I have an inexpensive CH compressor that runs good but takes a long time to build pressure as it seems to be leaking out of unloading valve while the compressor is running.
When the compressor finally reaches 125 psi it will shut off and hold the pressure and the leaking stops which tells me the check valve is functioning correctly.
The needle in the unloading valve needle is loose and simply moves back and forth in its orifice. is this supposed to be spring loaded or could the seat be damaged causing the leak?
