Central Illinois | Connect an air pressure gauge to the output of the air pump. It needs to be able to put out more pressure than the liquid pump. Have seen bad check valves allow liquid to back into the compressor and pit or seize the piston and cylinder. Also check the wiring and connections from the variable control to the compressor. You may not have enough juice to run the compressor to capacity. Steve | |
