Kyle, if your air tank has pressure in it, and you open that tank to atmosphere, air will flow out. Open the tank drain for a second if you want to see what I mean.

Therefore, if the air isn't coming out of the hose, and you have more than 15 PSI air pressure in the tank, you have a blockage in the discharge line.

Make sure the regulator is open (what pressure is on the gauge) as some of them can have the pressure turned down to zero, and then air won't flow through them.

Other than that, since I don't know what you've got connected up to the discharge port on your compressors, I can't comment on what might be stopping the air flow.

Cheers,

Bill
