Kobalt Pressure SwitchesDescription:
Make sure before ordering a pressure switch, that the check valve is not defective. Do this test first!! 1)Let your unit pump up and shut off. 2)Turn off compressor. 3)Find the large supply line that leads from the pump head into the tank. 4)Remove the supply line from the pump head. 5a)If you hear air coming from this line, then you have a bad check valve. Go to check valve page. 5b)If you do not hear air coming from the tank, you have a leaky pressure switch. Order a pressure switch or unloader valve.
