You might want to read up on them interesting "creatures" also read up on checking them ie: slack adjusters,air req. Good reading.
I based my answer on "seeing" part of an air chamber in the pic.
You need to drainthe tanks daily if using them...and every so often if it sits,water can buildup from condensation and rust/clog up stuff.
Make sure you have pressure built up and crack the valve on the tank.
You "should" have atleast two tanks....they both need to be drained(water can build up and take away from valuable air capacity and also rust out the tanks)
